Actor Johnny Depp has revealed that after four years of work, he has finally finished filming a documentary about the life of Keith Richards.

Depp tells Britain’s Even magazine,  “I’ve been working on it for about four years now and we’ve just completed the filming. Actually, it’s a little strange to call it a documentary, it’s more an opportunity to experience Keith – as people don’t get to see him because he’s quite a mysterious being. Essentially it’s Keith and I sitting around having a conversation and what it boils down to is his wisdom and his philosophy and his experiences – and that would be cut with footage of his life.”

“I feel blessed that this guy, who has never done anything like this before, has put his trust in me and allowed him to document his life. In some way – and I’m not comparing myself to him – I feel like Alan Lomax (music documentarian)… Doing this with Keith and recording how he thinks and how he looks back at 50 years of fame is pretty fascinating.”

Depp and Richards are longtime friends and, reportedly, it was Depp who got Keith his part in the two Pirates of the Caribbean movies.
