Inspired by @steamblust's JP Ceratosaurus comparison, I thought a little on thread on Ceratosaurus's appearances on the silver screen might be nice. (Sorry, '92's "The Dinosaurs!" We will skip TV for now.)

As far as I can tell, the earliest silver screen Ceratosaurus is from 1914's "Brute Force," the sequel to D. W. Griffith's "Man's Genesis." "BF" has the distinction of the first live action dinosaur, the granddaddy of Stan Winston's dinosaurs for "JP"—a life-sized Ceratosaurus.

The dinosaur munches on something (meat? grass? a caveman's shirt?) & spooks the cavefolk who hide. The movie also features a frilled boa constrictor & a horned alligator outfitted with 2 pairs of wings (!).

Ceratosaurus would not grace the screen again until 1940 in Disney's "Fantasia." It appears in the drought sequence at the end of "The Rite of Spring", menacing some mud-trapped herbivores.

I've discussed "Unknown Island" ('48) before, but hey, Ceratosaurus is in there, too—a whole squad of them in rubber suit glory.

1955: "Journey to the Beginning of Time" ("Cesta do pravěku") a Czech classic by Karel Zeman. Some boys journey down a river; the farther and farther they travel, the deeper into the past they go. In the Mesozoic length of the river, they watch a Ceratosaurus fight a Stegosaurus.

Zeman used Zdeněk Burian's art as inspiration for much of the film's creature design. Some of the animals even seem to be animated versions of Burian's paintings. However, Zeman's Stegosaurus & Ceratosaurus look little like Burian's take on the animals.

Burian did make a painting for the movie, featuring a Ceratosaurus more in line with the tubby fellow from the film. I don't know how this was used, if for a movie poster or preproduction art or...? It's a great image, though.

Irwin Allan brought "The Animal World" to cinemas in '56. Mostly documentary footage of wildlife, it did feature a dinosaur sequence showing various beasts in combat. The dinosaurs were animated by Ray Harryhausen & Willis O'Brien. Ceratosaurus stars.

A Ceratosaurus kills a Stegosaurus, but is attacked by another Cerato before it can feed. The two fight & (spoiler) fall off a cliff.

Allan was going to use still photos of dinosaur dioramas for the film, but Harryhausen convinced him that animation would be more memorable.

Some wonky-looking puppets were used for closeups.

Folks of a certain generation might know these scenes from Viewmaster reels.

In '66, a Harryhausen-animated Ceratosaurus graced the screen again in the Hammer classic, "One Million Years BC". The film's heroes Tumak & Loana hide from a battling Ceratosaurus & Triceratops. The Triceratops does better than the stegosaurs in the previous films—it wins.

Footage from the dinosaur fight was reused in "War Games" & the dinosaur episode of "Reading Rainbow".

Although a very Ceratosaur-like T. rex graced the cover of Edgar Rice Burroughs's "The Land That Time Forgot" (as painted by J. Allen St. John) no Cerato was found in the book. Not so for the 1975 film of the same name where one fights & loses to yet another Triceratops.

The creature effects of "TLTTF" were puppets designed by Roger Dicken. They have a fun, whimsical-yet-gorey quality, regardless of how convincing they may or may not be.

Dicken would later design the facehugger & chestburster for "Alien" & provide the creature with its voice.

"TLTTF" had a sequel, "The People That Time Forgot" (1977). A pair of Ceratosaurus made an appearance. I do not think Dicken had anything to do with them.

Ceratosaurus had a noticeable cameo in 2001's "Jurassic Park III", though it did little more than glare at the protagonists. Despite science's advances in how the animal actually looked, this Cerato still looked very much like a Harryhausen-style creature.

Let's end this thread with 2013's "Age of Dinosaurs," a movie I never saw & don't believe ever made it to the cinemas. I know this breaks my rule of no TV-Ceratosauruses, but I can't say no to Treat Williams. Get 'im, Treat!

That just about does it for silver screen ceratosaurs. Did I miss any?
