When young actress Saoirse Ronan wowed audiences with her turn in 2007’s Atonement, we expected many more fantastic performances to follow.  She’s done swell work in the meantime, with a standout role in last year’s Hanna, and now she’s gearing up to tackle one hell of a character.  Deadline reports that Ronan is attached to play the title role in Working Title’s Mary Queen of Scots.  There’s no word on how much of the dignitary’s life Michael Hirst’s (Elizabeth) script encompasses, but Mary was named Queen of Scotland when she was just nine months old.  Hit the jump for more.
