All the ones I'd mention already have been, but I'll recommend Duel and Enemy Mine, plus give a "so bad it's good" nod to Attack of the Killer Tomatoes (the theme song's cool, too!). Hunch over, it's time for another meeting!

Speaking of whom, how about The Golden Voyage of Sinbad with Baker as the bad-guy, Koura. Fun flick; by coincidence, it was Baker's next film after Frankenstein, both of which were before he has Dr. Who. The leading lady in the film was played by Catherine Munro, this also a few years before her best known gig on The Spy Who Loved Me. Of course the whole Ray Harryhausen line was fun.
