New York, Mar 14 : Actor-turned-rapper Joaquin Phoenix's fight in a Miami nightclub on March 11 was reportedly staged for a documentary by his brother-in-law.

A video showing Phoenix jumping into the crowd to attack a heckler at the gig is said to be a total fake, which has been staged for Casey Affleck's documentary on the actor's new career as a rapper.

The fight took place during his performance at a Belvedere IX party at Liv nightclub.

"But it was a fake fight," the New York Post quoted a source as saying.

"Nobody threw a punch. They were just holding onto each other," the source added. (ANI)
