Joaquin Phoenix's most recent movie director feels responsible for his bizarre career change.

Joaquin Phoenix has sparked fresh concerns for his mental health after a bizarre appearance on a TV show.

Joaquin Phoenix is "pretending" to have a nervous breakdown. The star - who is filming a documentary about his transition from acting to hip-hop music - is apparently faking his recent public outbursts for the film, directed by "Gone Baby Gone" actor Casey Affleck.

Joaquin Phoenix reportedly "stormed out" before a Las Vegas concert after losing his cool with a film crew. The actor-turned-singer is believed to have been furious when Casey Affleck's camera crew - who are documenting Joaquin's transition into music - were late for his sound check at LAVO nightclub last week.

Joaquin Phoenix is retiring from acting. The "Walk the Line" star - who was nominated for an Oscar for his role as country singer Johnny Cash in the 2005 movie - has revealed he is quitting the movie industry to concentrate on his music career.

Joaquin Phoenix was forced to miss the premiere of his movie "The Two Lovers" at the Cannes Film Festival on Monday due to the flu.
