Variety is reporting that Rupert Grint is one of the newest editions to the cast of The Drummer. The Drummer is an indie music biopic about Beach Boys drummer Dennis Wilson who passed away in the early 80s.  The film will go through the last six years of the musicians life and will start filming in mid-June.

Rupert is set to play Stan Shapiro, a mail room intern at William Morris, who befriended Wilson during the last few years of the musician’s life.

Rupert’s reps confirmed the news to Rupert-Grint.net earlier today.
