Affleck Helms Joaquin Phoenix Doco

Casey Affleck is set to direct a documentary feature on Joaquin Phoenix’s new career says The Hollywood Reporter.

Affleck is a close friend of the “Gladiator” and “Signs” actor who last spring decided to swap the acting business for a musical one.

Phoenix is embarking on a new path as a rapper, with an album to be produced by Sean Combs.

He is scheduled to make his first public performance Friday at a Las Vegas club, which will officially kick off Affleck’s shoot.
