Speaking on BBC Radio 2, he said he would be “flattered” if a similar film was to be made about his own career, and said he’d pick Notting Hill and Harry Potter actor Rhys Ifans to play him.
“Rhys would be a very good idea. [But] he has got to do something with his barnet,” Stewart said.
Ifans, who previously dated Stewart’s daughter Kimberley, also has musical experience of his own as a founding member of Welsh band Super Furry Animals.
Stewart also said he’d like his fourteen year old son Alastair to play his younger self, as he believes they have a “remarkable similarity” in their looks.
Stewart said: “If it does not happen it does not matter but I would be flattered if it did. But I tell you what, the Freddie Mercury one was so good. It was rock and roll. It would be hard to get something better than that but I would give it a shot.”
Earlier this year, meanwhile, Stewart was charged with battery after he and his son Sean were involved in an alleged fight with a security guard at a Florida resort on New Year’s Eve.
