Who Would You Cast as Kurt Cobain?

According to The Hollywood Reporter, filmmaker Oren Moverman is negotiating to direct the long-gestating biopic of late Nirvana frontman Kurt Cobain. Over at Popcorn and Prejudice, Seattle Post critic Moira McDonald asks, who should play the demigod of grunge?

Five years ago, Gus Van Sant cast Michael Pitt (pictured) as a Cobain-alike in The Last Days, a moody biopic speculating what happened during the musician's final hours. Pitt suggested that insular forcefield that was Cobain, and looked enough like him not to be distracting. I have no idea whether Pitt can handle the musical aspect, but he's an underutilized actor (see also Bertolucci's The Dreamers) and would be my first choice. Second: Emile Hirsch. As Jamie Foxx proved in Ray, you don't so much need to look like who you are playing as you need to channel him.)Who would you cast as Cobain? And who should play Cobain paramour Courtney Love?

Alternatively, most convincing performance in a musical biopic? Besides Jamie Foxx as Ray, I'm thinking Sissy Spacek as Loretta Lynn in "Coal Miner's Daughter," Reese Witherspoon as June Carter in "Walk the Line," and Forest Whitaker as Charlie Parker in "Bird." Also liked Judy Davis as Judy Garland in the telemovie "Me and My Shadows."
