CHRISTOPHER PLUMMER

The All the Money in the World star joins an all-star ensemble cast (including Daniel Craig, Jamie Lee Curtis, Don Johnson and Toni Collette) in the whodunit comedy Knives Out (in theaters Nov. 27). Plummer, 89, plays renowned crime novelist Harlan Thrombey, the patriarch of a family in which everyone’s a suspect after his highly suspicious death.

What kind of father do you think Harlan was for someone in his family to murder him? I think he was stern, bright and rough-hewn. He couldn’t stand that ghastly family of his. And he had a diabolical sense of humor.

Was it fun on the set with so many great co-stars? We all laughed a lot. And when you get a cast like that, it makes for more competition, and suddenly you’re really on your toes. You have to be. And that’s healthy.

Would you ever think about retiring? No, of course not. First of all, I can’t afford to retire, quite simply, and I don’t want to. Actually, I’ve done more interesting stuff in the last five or six years than I’ve done all my life in the theater. I don’t feel old. I’m in good shape because I go to the gym and I do all the right things, play tennis and walk. No, never retire. Don’t want to. There’s too many wonderful things to do.

If you could go back and give advice to your younger self, what would it be? Stay as sober as you possibly can.
