Well, I feel like a total schmuck for never noticing the elemental parallels until now. But now that it has been pointed out, DOY!, it's so obvious!!!
But what were the parallels Beaker hinted within the first post, beyond a grouping of four people? I've never seen "Angry Red Planet", so I'm again clueless? was it just their personalities and job functions, or did something affect them during the course of the film?
