On of my favorite 70s films was “Marathon Man” (1976, Paramount), by John Schlessinger, based on the novel by William Goldman.
The greatest scene is the “Is it safe?” inquisition where Babe (Dustin Hoffman) is tortured by a dentist disguising his identity as a Nazi war criminal (Szell, played by Laurence Olivier).
Babe is a doctoral graduate student in history, Doc (Roy Scheider) is his brother, and Elsa Opel (Marthe Keller) is the girl friend, and Chen (James Wing Woo) is the rogue assassin (a kind of Pie-o-Pah).
I saw the film in midtown Manhattan in a large palace in the fall of 1976.
