Time Travelers (TV-movie, 1976)

Time Travelers is pretty unusual - you don't get many collaborations between Irwin Allen and Rod Serling. It’s a TV-movie that was actually made in 1976 as a pilot for a projected Irwin Allen television series that never eventuated.

What's most surprising about this production is that it's actually quite a decent (and even moderately intelligent) science fiction movie.
