The Incident (1967)
On a New York City subway, two young punks, Artie Connors (Martin Sheen) and Joe Ferrone (Tony Musante), take control of a car filled with passengers. Among other people, the train includes military officer Felix Teflinger (Beau Bridges) and tough-talking Bill Wilks (Ed McMahon), as well as quiet Jewish man Sam Beckerman (Jack Gilford), and his wife, Bertha (Thelma Ritter). As the hostage situation stretches out, things become increasingly tense for everyone confined to the subway car.
Great cast of character actors (and Ed McMahon) with great shots of the Bronx in the late 60's, film has a kitchen sink drama feel that would have been much more of an exploitation film had it been made 5 years later, but as is, has some sort of aspirations to a theatre like respectability (mixed with a little B-movie sleaze)...
