I used to watch a lot of the old black-and-white "prehistoric " movies as a kid, but they are now pretty much jumbled up in my mind. I remember some of them actually had pretty good special effects (for the time they were made, at least!), while others were truly horrendous! Some of them had real lizards with spines attached to them to give them the “prehistoric” look; others just had really bad, ridiculous-looking dinosaur suits! Could somebody with a clearer memory than mine help me out here? What are some movies with really crappy looking dinosaurs?
Really bad live action dinosaurs can be found in The Land That Time Forgot (indeed any dino movie starring Doug McClure). They are possibly the nadir of lizards with fins technology.
If you want bad puppet dinosaurs, then how about Reptilicus
Alas, both of these films are in colour.
The Lost Continent might fit the Black & White bill.
Another color dinosaur turkey, The Last Dinosaur, a retched TV movie starring Richard Boone, Joan Van Ark, and a T-Rex that looks like it would be more at home as part of a small town homecoming parade float.
Just above the nadir of “lizards with fins technology” (great phrase) would be the The Lost World (1960-ish), and One Million Years B.C.
King Dinosaur used lizards without fins, and claimed that an iguana was a T. Rex.
The random dinosaur scenes in Robot Monster were … pretty damn cheesy. Strangely, Dinosaur Island, a softcore take on the dinosaur theme, had dinosaurs that, while bad, were better than most of the ones cited here – and they had T&A to sort of spackle over their cinematic lapses. What was the one by the Russians about the exploration of Venus that had hot blondes and dinosaurs inhabiting the planet? I remember they had a rubber pterodactyl that was just … totally lame.
You’ve gotta get The Last Dinosaur, but why take my word for it, when so many IMDB users concur?
Seriously, though that dorsal tail seam on the T-Rex was hilarious, and I remember that forehead-denting.
What was the name of that one movie… mid-fifties, I think… where the T-rexes were in fact guys in very tall suits?
That’s almost certainly The Lost Continent I mentioned above. Suits (cardboard) around 6’6" high .Please don’t re-watch it, I value your sanity too much.

These aren’t even in the running. How abou:
Unknown Island – tyrannosaurus Rex done by guys in really bad monster suits. *Light years[/i[ worse tha The Last Dinosaur
King Dinosaur – the T rex is a very un-T-rex-like lizard.
The Lost World The 1960 version. Blown-up lizards sub for dinosaurs.
**One Million B.C. ** – the Hal Roach 1930s version, not the Raquel Welch version. The original flick with lizard dinosaurs. Animal were hurt in the making of this film. The footage showed up in a lot of films after this, including Robot Monster. One illion B.C. also gives us a giant armadillo, and a pig dressed up in a triceratops suit. (!!!)
But the winner for worst dinosaur effect is:
The Prehistoric Sound. Spanish film with several alternate titles. The dinosaur is invisible (except for the last few seconds). A real savings in special effects. Also features the worst “invisible” special effects you’ll ever see.
“Rock climbing, Joel.”
So it was good for one thing, anyways…
And yet, some of htose old movies had darn good effects, considering.
The Valley of Gwangi, if you’re wondering.
Nope. It’s Unknown Island. The Lost Continent, though pretty bad, at least featured stop-motion animated dinosaurs. (“This is the COOL part”: Crow)
Teenage Caveman has lizards-as-dinosaurs, plus guys in rubber suits playing dinosaurs. See the middle picture in the 3rd row down at http://fast.horrorseek.com/horror/tonyrivers/caveman.html to enjoy the goofiness.
…although now that I read back over this thread, I’m amazed no one’s mentioned the legion of men in rubber suits that represents Japanese dinosaur/monster cinema…
…But they have, however indirectly. The Last Dinosaur farmed out its special effects to Japan, and used a combination of techniques, including men in foam-rubber suits, to inadvertent comic effect.
The Land Before Time 1-6
Those things haven’t looked real since the first movie.
I like the alligator dressed up as a Dimetrodon.
I know it’s not a movie, but has anyone considered the old Land of the Lost TV Series (by the Kroffts)?
