And Sophie Turner is keen to take on the challenge too.
After seeing British Vogue tweet out the news, Turner responded saying she would be "SO down" to play the role.
Meanwhile, the Karma Chameleon hitmaker suggested he didn't care if the movie wasn't entirely truthful because he loves reading "ridiculous" rumours about himself.
He said: "In our game, there is always stuff that is written about you that is so ridiculous. That you say, 'I don't mind it though, it makes me sound more interesting.'
"He sleeps upside down on the roof. He only lives on lentils, that kind of stuff. I think it just makes a great picture."
It was previously reported that the untitled film will chart the 57-year-old singer's childhood in a working class Irish family through his rise to stardom along with Culture Club in the 1980s.
As well as Sacha, Kevin King Templeton and Paul Kemsley are on board to produce while George and Jessica de Rothschild will serve as executive producers.
It is not yet known when the movie will be released.
