Susan Boyle, the 52-year-old Scottish singer whose 2009 performance of "I Dreamed a Dream" received a standing ovation on Britain's Got Talent -- both because she was talented and because the judging panel seemed surprised that a dowdy middle-aged woman could sing.
"I wouldn’t like to be in the film myself," Boyle said. "I’d like someone to play me. Probably Meryl Streep -- I understand she has been approached."
While this is obviously an unconfirmed rumor and Streep's name gets tossed around for biopics about any woman of a certain age, she does have the singing chops. The actress played Donna in 2008's film adaptation of Mamma Mia!
