Marc-Antoine Audette, a Montreal radio personality known locally as half of the duo Masked Avengers, pretended to be the film's award-winning actor Jean Dujardin in a telephone call to Sheen, once television's highest-paid actor.
He told Sheen in an exaggerated French accent that he wanted to make a comedy with him to raise money for a foundation against dictators.
Sheen congratulated Dujardin on his Oscar win.
“Thank you for considering me, that's very sweet,” he also said, accepting the offer despite at times being unable to understand what the caller was saying.
Sheen earned $2 million per show for his role as a hedonistic bachelor in “Two and a Half Men” but he was fired for slamming its producer Chuck Lorre in a rant described by his bosses as part of a “self-inflicted disintegration.”
The two Montreal pranksters have also snared Bill Gates, Britney Spears, Paul McCartney, even Sarah Palin during the 2008 US election, in their gags.
