REMEMBERING ROD SERLING: Requiem for a Heavyweight (1962-95 min.). Louis “Mountain” Rivera (Anthony Quinn) is at the end of his boxing career, sporting cauliflower ears and a damaged eye, but his manager Maish Rennick (Jackie Gleason) can’t admit that he’s gambled away all of Rivera’s winnings. To save himself from mobster goons, Maish must talk his proud palooka into signing a contract to perform as a wrestler. Mickey Rooney co-stars as Army, Mountain’s cut-man, and Julie Harris plays sympathetic employment counselor Grace Miller. Ralph Nelson directed, from a screenplay by famed television, radio and film writer Rod Serling, who passed away on this day in 1975. 7:30 p.m.
