Russell Brand To Play Sparrow's Brother In "Pirates 5"?

A few years back, before "Pirates Of The Caribbean: On Stranger Tides" went into production, Russell Brand was rumored to be taking part in the film. He confirmed that he was in talks with the studio, but couldn't do it because he was working on "Get Him To The Greek".
Now, according to movie insiders, Brand is said to be in talks again for a role in the next "Pirates" film. He's in talks for the role of Captain Jack Sparrow's younger brother. All we need is the mother and the family is complete. We have Johnny Depp as Jack, Keith Richards as his father and now the rumor of Russell Brand playing his younger brother.........AWESOME!!!!
