The 1970’s were Peak Made for TV Movies, and they tended to fall within three camps:
You had the good – Brian’s Song, a true story about the death of the Chicago Bears football player, Gayle Sayers – the one movie that made every man on the planet cry before Spock’s death in the Wrath of Khan came along.
You had the hidden potential – Duel, a young Steven Spielberg’s first foray into full length film that pitted ol’ Marshall McCloud himself, Dennis Weaver, against a homicidal big rig driver who just will. Not. Die.
You had the springboard – Shows such as The Night Stalker and Columbo came from Made for TV movies.
