This is from the same movie the hippo shot last Friday came from. The suit looks pretty shoddy, but the make-up is actually pretty good for a film with this budget. Here's a publicity still I found giving us another (perhaps too) good look at the monster.
We've seen some of the earliest stop-motion dinosaurs this week. This is one of the earliest slurpasaurs. Amazing to think this sort of thing remained in use through the '60s, and in some fairly big budget movies.
I'm thinking they had a lot of fun designing these monsters. And they have a real mythic feel, what with the mixing of different kinds of animals. I like how the scientist is pointing out the fight. Otherwise I'm sure she never would have noticed it.
This is a nice addition, since it adds super-science to the post-apocalyptic landscape. I wonder if this was a leftover of a previous age, or the work of a contemporary mad scientist.
