After The Sopranos, my mother said, "Couldn't there be some raft floating under the bridge when you jumped? Or couldn't you have a twin brother?" I said, "Yeah, if they'd wanted me that bad. But they don't."

There were a lot of things in it that were important at the time to me. Cutter's Way movie was very relevant. And I wanted Cutter to succeed as a vet, as a guy coming back from 'Nam, because there were so many guys like that. And there were so many other movies at the time, like Apocalypse Now, Coming Home, and The Deer Hunter, that it was really important that the movie be believable, that I come across a pissed-off vet who'd been there and comes home angry.

When my agent called me up and said, "Do you want to be in a movie called Sharknado?" I said, "What is it about? Is it really about sharks falling out of the sky and eating people?" And she said, "Yes." And I said, "Definitely. That is going to be a huge hit. That is going to put to rest the Home Alone dad image. I'm going to be the Sharknado drunk instead, hopefully." And I was right. I don't know how I knew that, but I just knew that Sharknado was going be a huge hit.

I remember one afternoon when we were out on a golf course somewhere, and Lauren Bacall, James Garner, and Jack Lemmon were sitting there in deck chairs when I went off to do another scene. And I said something like, "Hey, where have you guys been?" And they said, "Oh, we were down at the clubhouse. We saw your scene!" And Jack Lemmon looked at James Garner, and James Garner looked back at me, and then they both looked back at me and said in unison, "You bet your ass it is!" So I've been up there with the greats. I've had my fleeting moments with theatrical genius.

Griffin Dunne and I were both terrified that Martin Scorsese didn't think we were very good - and if he didn't think we were very good, that was it. That was the end of the line. If Martin Scorsese thinks you stink, you stink.

Cutter's Way was a real test of my stupidity. Every day, it was like, who did I think I was? But people put up with me. But I considered myself an alcoholic, so I had the inside track on how an alcoholic would do this or that and so on and so forth. That became pretty annoying, I'm sure.

They killed me in The Sopranos. I went to David Chase, and I said, "Why me? I'm a detective! You can use me forever!" And he told me, "John, there's a rule in television: Somebody has to die that the audience likes."
