Watson tweeted: I’m filming Perks of Being a Wallflower this summer. Can’t wait! x.
The 20 year-old has reportedly been considering the role in the Stephen Chbosky adaptation since May. She will play the role of Sam, the first love of the main character, Charlie.
The story, told through the perspective of a teenage outcast, is considered a movie that deals with some “mature content”.
Production is scheduled for this summer and the movie is tentatively due out in 2012.
