Your performance in Silver Linings Playbook has been hailed as one of your best in years and it's attracting some Oscar buzz. How did you get involved?
I'd been talking with David [O Russell, the director] over the years but we hadn't worked together. Then he made The Fighter, which I thought was terrific. He had this other project and he wanted me to play the father. I said I'd do it. That was before David rewrote it and my character changed. He kept to himself more in the book it was based on and was more angry but he didn't have many other colours. I liked what David did: he kind of reversed him, pulled him inside out. He's a guy who has some obsessive compulsiveness. His son [played by Bradley Cooper] has that too but his is more extreme.
Was there a good father-son dynamic on set?
Yeah. Bradley and I became friends. Even if we weren't that way it still would have worked out but a built-in relationship definitely doesn't hurt.
Do you feel pressure to be a wise godfather figure to all these younger actors who look up to you?
I don't feel pressure. I like if anybody has interest in what I have to say, especially if they're younger. If they like me, respect me, I'm honoured and I'll give them my opinion.
You made eight films with Martin Scorsese, starting with Mean Streets in 1973, but you haven't worked together since Casino in 1995. Is a reunion likely?
Oh yeah, we're working on something now. It's called I Heard You Paint Houses. We've been trying to get it going for a couple of years and now we're just trying to set a time. It's about a guy called Frank Sheeran who was in the Teamsters [a US union] and claimed to have killed Jimmy Hoffa [the controversial union leader who disappeared in 1975]. It's based on a book by Charles Brandt who was Sheeran's lawyer. I'd play Frank Sheeran and Pacino would play Hoffa. Joe Pesci would be in it too.
