Depp 'making Keith Richards documentary'

Johnny Depp has started work on a documentary about Rolling Stones guitarist Keith Richards, says Pop Sugar.

It is widely known that Depp's Jack Sparrow character from Pirates of the Caribbean was modelled on Richards.

The actor also has other music-related projects in the works. He is reportedly teaming with Nick Cave and Shane MacGowan to record a charity single for Haiti earthquake relief.

Meanwhile, Ozzy Osbourne wants the Edward Scissorhands star to play him in a biopic about his life.
