Chloe Moretz and Rupert Grint have signed on to join Aaron Eckhart and Vera Farmiga in the The Drummer.  Director Randy Miller's indie music biopic focuses on the last six years life of Beach Boys drummer Dennis Wilson (played by Eckhart).  As we reported in January, Farmiga will play Fleetwood Mac singer-songwriter Christine McVie, who sparked a passionate and tumultuous relationship before Wilson’s death in 1983.  According to Variety, Moretz will play Wilson's daughter Jennifer, and Grint has been cast as "Stan Shapiro, a mail room intern at the talent agency William Morris, who befriended Wilson during the last few years of the musician's life."  Jennifer Wilson is co-producing the film along with her half-brother Carl.

Filming is set to begin June 15th.  Moretz will next be seen in Tim Burton's Dark Shadows.  The Drummer will be Grint's first major role since Harry Potter and the Deathly Hallows – Part 2.
