Johnny Depp to Direct Keith Richards Biopic?

It's been announced that Johnny Depp will direct a documentary about musician Keith Richards (who played Jack Sparrow's father in Pirates of the Caribbean). Depp says:

Now that I’m wiser, and that enough time has passed, I can experience directing again. Already next week I’ll start working on a Keith Richards documentary. While I’m in Drvengrad, my editor is already working on kilometers of archive footage and footage of his concerts. I’m very touched that Keith agreed to show up in front of my cameras.
