Ghostbusters star Bill Murray has opened up about what attracts him to playing troubled characters in his films.

Murray, who revealed he doesn’t have an agent anymore, is at the festival promoting his upcoming indy flicks “The Friend” and “Riff Raff.” When asked about playing characters who “lead lives of enormous charm” and being “aware of how poisonous their charm can be,” Murray didn’t hold back.

Bill Murray used to be a staple of Hollywood between the late '70s through to the '90s. He has a slew of fun vintage Murray movie quotes and was one of many SNL stars who made a great return to the late night series.

Bill Murray is coming clean about past instances of questionable behaviour — albeit without going into specifics. Murray, 74, made an unscheduled appearance at the Sundance Film Festival on Sunday and spoke about his film career and roles playing complex characters.
