"Harry Potter" star Rupert Grint has just signed on to the Dennis Wilson biopic "The Drummer."
According to Variety, Grint has been cast as Stan Shapiro, a mailroom intern who befriended the Beach Boys drummer a few years before his death. Joining Rupert will be Chloe Grace Moretz, who'll portray Wilson's daughter, Jennifer.
Set to begin production this June, "The Drummer" will focus on the last few years of Wilson's life (he passed away in 1983). Aaron Eckhart has already been cast as Dennis; Vera Farmiga will play Fleetwood Mac member Christine McVie, who had a relationship with Wilson before his death.
