Don Rickles was probably one of the few people on Earth who could get away with insulting the director, something Martin Scorsese admits he did often.
Martin Scorsese issued a statement (via Rolling Stone) honoring Don Rickles, who once starred in Scorsese’s 1995 film, Casino.
Afterward, Rickles and Scorsese stayed in touch and became close friends.
Scorsese highlights the experience of working with Rickles in his statement, noting how professional he could be while being hysterical every day on set.
