He was a great character actor. I remember him in the 1967 movie, "Wait Until Dark" with Audrey Hepburn and Richard Crenna.
Yeah, I was reading on IMDB.com that he said he really hated that role because he liked her a lot. My favorite movies with him were “Catch 22” and “Grosse Pointe Blank”.
I remembered him because of his performance in one of his first movies, "The Heart is a Lonely Hunter," 1968. Good film.
