Robin Williams as Susan Boyle?

Robin Williams doesn't seem to mind being typecast as an older Scottish woman—but might Scottish women get sick of being played by Williams? In 1993, the comedian memorably portrayed prim nanny Mrs. Doubtfire, and now he's been approached to play Britain's Got Talent sensation Susan Boyle in an upcoming film about the singer, The Telegraph reports. "I think she’s incredible," Williams, 57, said. "So inspiring." He has apparently been doing impressions of Boyle singing "I Dreamed a Dream," the song that made the 48-year-old famous.
