Love the movie, but did Michael Criton steal the idea?
I'm not trying to take a jab at the truly talented novelist that wrote the incredible story on which the film 'Sphere' is based but I'm wondering if he got his ideas from somewhere else.
This film

Galaxy of Terror seems like a mediocre, low budget horror flick but the synopsis says that the crew of a spaceship discover an alien pyramid that causes the crew's worst fears to physically manifest themselves. It sounds an awful lot like Sphere.
