Thoughts On: “The Lost World” (1925)

While its embarrassingly belated due to not having a speck of spare time over Labor Day weekend or much in the past week (man, I hate being busy), this is officially the last post of Silent Stop Motion Month! I hope you enjoyed the series as much as I enjoyed researching and writing about it. It’s back to “normal” for awhile, but don’t forget…October Is Coming! 😉

In a world overflowing with dinosaur toys, books on prehistory, fossil exhibits, and Jurassic Park movies, dinosaurs are so popular that its hard to imagine life (or our childhoods) without them.

…Some folks have a harder time imagining it than others.

So difficult as it may be, try to picture a time when dinosaurs weren’t rampaging across our screens, a time when the illusion of prehistoric monsters coming to life was something very new…and exciting. After all, the scientific study of dinosaurs as we know it today had only been around since the 19th century, gaining steam during the Gilded Age. It would take a visionary like Willis “Obie” O’Brien to take his boyish enthusiasm for these long-gone creatures and figure out a way to bring them to the big screen.

Obie, as he was nicknamed, was a restless young man from southern California who had drifted through a series of jobs, from sports cartooning to professional boxing to being a brakesman for the Southern Pacific Railroad. One experience that had stuck with him was acting as a guide for a group of paleontologists. Watching them examine the Crater Lake area for elusive dinosaur fossils fascinated him, and this interest would prove key to his later career.

He eventually ended up in a marble sculpting shop where he sometimes made clay models. Being an avid film fan, it occurred to him that he could animate these models on film. Excited by the possibility, he rented a little shed on the roof of a San Francisco building and started experimenting with a hand-made brontosaurus model. One way or another, he just had to bring these fascinating prehistoric creatures back to “life.”

Obie’s first complete short was The Dinosaur and the Missing Link (1915), a five-minute short about four cavemen that took him two months to complete. Its success lead to Birth of a Flivver (1916) and several other “Stone Age” shorts, one of the most interesting being The Ghost of Slumber Mountain (1919). But short films weren’t enough for the ambitious young animator–since its publication in 1912, he’d been obsessed with Sir Arthur Conan Doyle’s sensational novel The Lost World. In a sense, the years of painstaking work were preparation for his dream project, a feature-length adaption of the classic adventure story.

His employer Watterson R. Rothacker had the film rights to Sir Arthur Conan Doyle’s work (one wonders if Obie purposefully worked for Rothacker because of that!). He agreed with Obie that a feature film of The Lost World would be a very exciting project, and thus, work on the ambitious monster movie began at the Brunton Studio in Burbank.

Chosen to be the (human) leads were character actor and frequent screen villain Wallace Beery, gentlemanly Lewis Stone (later Judge Hardy in the Andy Hardy films), wholesome actress Bessie Love and the clean-cut Lloyd Hughes. The real stars of the film, of course, were Obie’s dinosaurs, which he animated in a small studio away from the main stages.

He diligently worked on around 50 model dinosaurs–even today this is a lot of puppets for one stop motion film. With the help of assistants Marcel Delgado and Ralph Hammeras, Obie designed ball-and-socket skeletons for his models, overlaid them with rubber muscles (for more realistic movements), and used latex rubber for the exteriors. As a final life-like touch, small bladders were placed in the chest areas of the creatures to simulate “breathing.”

The miniature jungle sets were about six feet long and five feet wide, lit by Cooper-Hewitt mercury vapor lights. (Some of the decor was made by sowing grass seed, which grew quickly under the lights.) The largest set, which would feature an impressive dinosaur stampede, was 150 feet long and 75 feet wide. It took Obie and his assistants a painstaking 960 frames of film to achieve one minute of stop motion footage–truly herculean effort–and temporary walls were put up around the set being used to ensure complete solitude and concentration. On top of all that, the models experienced frequent wear and tear and by the end of a long day’s filming had to be repaired for next day’s work.

Some of the wear and tear.

The result, while it can appear a bit crude today, was groundbreaking in its depiction of dinosaurs as energetic and fast-moving (instead of lumbering and sluggish). Obie had a remarkable eye for giving his prehistoric beasts believable, animal-like behavior, and his animated sequences are full of inspired touches like the tail of an edmontosaurus rippling while it dies, or a triceratops nuzzling her baby offspring after fending off a predator. And, in a prescient move, he makes it clear that the explorers are safer while observing the plant-eating dinosaurs, just like Jurassic Park would decades later.

The Lost World (1925)

The scenes of humans and dinosaurs in the same frame were difficult to do, but are surprisingly well done, involving careful use of matting. One standout scene shows an allosaurus sneaking up on the explorers’ campground. They open fire and throw a flaming log at the creature–who catches the log in his (rather slobbery) mouth.

As a whole, The Lost World is a fairly faithful recreation of Conan Doyle’s novel, with some inspired additions. While in the novel it was a pterodactyl that confounded London, in the movie a full-grown brontosaurus rampages through the city, in a highly-original clash of the ancient and the modern–it set the standard for umpteen monster movies to come.

There are some clumsy moments–especially when the head of a surveying expedition, who we’ve never seen before, simply walks into the frame just when the explorers need him–but overall it’s a good-looking thriller (thrilling, that is, in its 1925 way) that revels in its exotic locations. I love the lush shots of the miniature jungle, which have the exact dreamlike quality we might recall from our own imaginations while we were reading classic adventure stories.

The Lost World was a resounding success, in both the U.S. and abroad. Sir Arthur Conan Doyle himself gave it his stamp of approval, both by briefly appearing in the beginning of the film and by showing some of the footage to the Society of American Magicians in New York (boasting it was a kind of magic that would make their illusions seem “tame”). There had never been a feature quite like it before–and it no doubt transfixed an entire generation of children.

Obie’s followup to The Lost World was originally a similar film called Creation, but when RKO put the kibosh on it, he used his ideas for an even bigger picture: the one and only King Kong. And we all know how that turned out!

There’s a fitting coda to the production of the ambitious The Lost World, which Obie himself would probably find amusing. Several of the original dinosaur models were donated to the Museum of Arts and Sciences at Exposition Park in Los Angeles, where their latex skins slowly began to deteriorate as the years went by. Put into storage, they were accidentally walled up when a new wing was added to the museum. I’ve heard that a few models (mostly surviving as metal skeletons) have been “rescued” since then, but there may be more still waiting to be uncovered–rather like those lurking dinosaur fossils around Crater Lake that had fascinated O’Brien all those moons ago.


My main source for the articles in Silent Stop Motion Month is the wonderful book A Century of Stop Motion Animation: From Melies to Aardman by Ray Harryhausen and Tony Dalton. Highly Recommended!


  • The Lost World was chosen to be the world’s first in-flight movie, being shown on an Imperial Airways flight from London to Paris in April 1925.
  • Some of the models were later collected by Forrest J. Ackerman.
  • An early prologue that was lost showed Conan Doyle examining Obie’s models before sitting down at a typewriter to write The Lost World. 
  • Parts of the original novel dealt with a prehistoric “ape man” culture, but the film simply had a few scenes featuring one ape man.
  • Melted dark chocolate was used for the “blood” in scenes where dinosaurs were wounded, and saliva was achieved with a type of varnish.
  • Some of the miniature sets had openings hidden behind hills and trees, where the animators could reach through to adjust the models.
  • The flaming log the allosaurus catches in his mouth probably had pointy metal pieces on its ends, animated to look like flickering flames.
  • During the London scenes we see a theater marquee advertising The Sea Hawk, which both Wallace Beery and Lloyd Hughes were appearing in.
  • The legendary stop motion artist Ray Harryhausen had fond memories of seeing Obie’s dinosaur models on display during the early 1930s, and of the film itself. He would recall: “It was in 1925 that I saw The Lost World. This was heady stuff for such a young mind… Although I was only five at the time, The Lost World made a huge impression on me, especially the scene where a huge brontosaurus falls off the plateau and into a lake of mud where it lies struggling… The image of that brontosaurus kept reappearing in my mind’s eye, and from that moment I knew I wasn’t alone in my fascination with dinosaurs.”

  1. Wow, Leah, you sure did it again. “The Lost World was chosen to be the world’s first in-flight movie, being shown on an Imperial Airways flight from London to Paris in April 1925” Talk about going the extra mile on information! Fascinating; when I saw it, I was surprised at how great the special effects were, comparing it (favorably) to “King Kong”.

    He gets so much emotion out of his dinosaurs and monsters! That’s what’s missing from the CGI stuff! And the movements and situations are all plausible….as opposed to Naomi Watts and company running under a stampeding herd of Brontosaurs’!

    The nuzzling of the baby offspring is a perfect example, I remember being so struck by that.

    As usual, you give us that extra special tidbit…..that the models were walled off, waiting to be discovered, like dinosaur bones themselves! I’m shaking my head in disbelief. What a world we live in.

    • Strange as it may seem, the cruder, stop motion creatures in these films do have a bit more emotion than a lot of CGI animals–maybe because CGI can look SO realistic that you really can’t give them humanlike expressions. A perfect example is the new “live action” (actually CGI) THE LION KING. Exact same shots, exact same situations, barely any emotion. (Why they made it is beyond me!)

      That bit about the trapped dinosaur models is one of my favorite pieces of trivia. What an appropo fate!

      • Stop the presses! I just remembered an exception to the rule: the dinosaurs in “Tree Of Life” are definitely special, demonstrating mercy. I thought that was a beautiful one-of-a-kind film, as well. Like “Sunrise” for the 21st century!

        Ugh! Remaking “The Lion King” live action/CGI…..yes, WHY? What the….?!!!!

        We need mavericks back in Hollywood, its just so pitiful what’s happened with movies. Just a dearth of ideas. “Make The Movies Great Again”, I’m having a hat made at once! lol. (i’ll make two hats, I’ll send you the other) 😉

        I love that clip when Lillian GIsh got up at the Oscars, or wherever it was, and told the crowd that they needed to bring silent movies back, lol. And they cut to John Huston sitting in the audience, and he’s kind of nodding, like…..”she may have a point there!” 😀

        • If I were to pick some of the best 21st century movies, they would include: Pixar films (especially the era of WALL-E and UP) and PIRATES OF THE CARIBBEAN: THE CURSE OF THE BLACK PEARL, a perfect piece of fun escapism. And a bunch of the Marvel movies. Yes indeedy! All those films, all those characters, all those storylines, and nearly everything was well done, thrilling and entertaining? Amazing.

  2. I’m so glad and amazed that you chose to write about this film! I’m currently doing some research on Marion Fairfax, who wrote the screenplay, in an effort to mark her grave. I plan to watch this movie soon, but I’m glad that you helped give me some background on it first!

    • Hello Samantha ! – just found your post today. i read years ago that during the production of “The Lost World” Ms Fairfax actually suggested to Mr OBrien that if necessary the film could be completed without any of his dinosaurs (the 49 metal-armatured animation models which he had Mr Delgado build for the filming) !!! after the release of the film, a number of those ani-models were donated by Mr OBrien to the natural history museum in LosAngeles (which displayed them for several years, and then later loaned them to the SanDiego natural history museum), but it seems today no one knows (or ever investigated) what ultimately happened to them. a year ago i had posted an inquiry about it on FB, but apparently its another unsolved ‘Hollywood mystery’. have you read or heard anything about this ?
