Oldman and Bowie have been friends for decades, and united for the promo clip for the title track from Bowie's 2013 comeback album - sparking controversy by showing Bowie as a Christ-like figure and Oldman as a corrupt priest.
Speaking the Daily Mail's Event Magazine about how he landed the role, Oldman said: "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."
When asked about the controversy surrounding the video, Oldman replied: "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."

Not only was the video temporarily banned from Youtube, but it also attracted criticism from the Christian Right, leading the Catholic League to brand Bowie a"switch-hitting, bisexual senior citizen from London".
Gary Oldman also spoke to XFM about his friendship with Bowie, saying: "I've known... David's a friend of mine I've known him 30 years. We were [out on the town] recently actually, in New York" - adding that they went out for lunch.
When asked what the pair had to eat, Oldman replied: "Erm... Sushi."
This is the stuff that rock legend is made of.
