I believe this has never reaired, so it's probably a longshot. Karras plays a hillbilly weightlifter at the 1972 Olympic Games in Munich. It was shot on location during the games. For those of you too young to remember, these games were tragic, as PLO terrorists entered Olympic Village and held some Israeli athletes hostage. They would later be killed. See link:

On the bright side, American swimmer Mark Spitz would win 7 gold medals and set world records in the process.
