Irwin Allen
There's been a lot of discussion on this board about the influence this movie had on Ridley Scott's "Alien", which may well be, but after watching this movie I couldn't help but believe it influenced producer/director Irwin Allen as well.
The vast sets, wacky science, rubber suited monsters, crawling around in air vents, and two dimensional characterizations would all be hallmarks of Allen in years to come.
I think what made me tumble to it the most was the Paul Sawtell music, in fact watching this movie just made me think of it as an episode of Voyage to the Bottom of the Sea. Which is a good thing, it made me like the movie all the more.
