Magnolia Pictures has released a clip featuring music mogul Sean 'Diddy' Combs from the directorial debut of Oscar-nominated actor Casey Affleck, 'I'm Still Here.'

The documentary is a striking portrayal of a tumultuous year in the life of internationally acclaimed actor Joaquin Phoenix. With remarkable access, 'I'm Still Here' follows the Oscar-nominee as he announces his retirement from a successful film career in the fall of 2008 and sets off to reinvent himself as a hip hop musician. Sometimes funny, sometimes shocking, and always riveting, the film is a portrait of an artist at a crossroads. Defying expectations, it deftly explores notions of courage and creative reinvention, as well as the ramifications of a life spent in the public eye.

In this clip, Phoenix is looking to bring Combs on board to produce his album.

'I'm Still Here' opens in select theaters on September 10.
