Gary Oldman took part in his friend David Bowie's video for his single The Next Day "for a sandwich and a bottle of pop", he has said.
The pair have been friends for 25 years and he did the video for him last year as a favour.
He told The Mail on Sunday's Event magazine: "Dave just shot me an email, out of the blue, saying, 'Do you want to come and play a priest for a day?'
"It was all done for a sandwich and a bottle of pop. We actually shot it in a place that's about 10 minutes from my house. There was no money in it."
The video featured Bowie as a Christ-like figure with Oldman as a clergyman leading a woman into what appears to be a brothel, punching a beggar at the door and picking up a prostitute, played by scantily clad Marion Cotillard.
It attracted criticism in some quarters but Oldman said: "People can make what they want of it, that's the point of a video like that. He's an artist, he makes you think.
"I was thrilled when he released the new album last year. I was talking on the phone to him and he said, 'I don't know about touring. I have no great desire to get out there again at the moment.' And I said, 'But you're writing again?' And he said he was. I think we'll probably see him again. He's planning something."
Oldman, who has made three films in the past year, said he had to be careful "because otherwise it's too much".
He said: "Marlon Brando said that as an actor you've only got so many faces in your pocket."
Asked if he could see a time when he would stop acting, he said: "Oh absolutely. I'd probably have walked away from it many years ago if I'd had the money. But I wouldn't just sit around - I'd do other things. I've got a new script that I'm trying to put together. I like photography and I want to direct."
