Following his Harry Potter role as Ron Weasley, Rupert Grint will join The Drummer, the biopic about Dennis Wilson, the Beach Boys drummer and brother to fellow band members Carl and Brian.
Chloe Moretz (Hugo) has signed on for the film as Wilson's daughter Jennifer. Aaron Eckhart (Battle: Los Angeles) plays Dennis Wilson during the six years before he died in 1983.
Vera Farmiga will play Christine McVie, the singer-songwriter and keyboard player of Fleetwood Mac, who had an affair with the drummer, which may have inspired her song 1982 Hold Me.
Grint's taking the role of Stan Shapiro, a young mailroom intern at the William Morris management company, who became a close friend to the drummer during that final spell of his life.
Director Randall Miller (Bottle Shock) co-wrote the script with Jody Savin. Production starts in June.
