Did you notice that his character in Marathon Man was gay? When he is on the phone to "Janie", and says "get your ass over here, I wanna see you!", he is on the phone to Janeway, the character played by William Devane, and presumably, his lover.
I remember Scheider primarily for All That Jazz. He was also a typical Hollyweird leftist.
I love that movie, but that point never dawned on me. Wow, the things that you learn later./Just Asking - seoul62.........
Whatever! You know, the man is dead. I don't really care what his politics were. I liked him as an actor in the few things I saw him in. Prayers for his family in their time of sorrow.
