Mick Jagger might be getting back into acting.  The Rolling Stones singer is considering playing a media mogul in Tabloid, a new movie being developed by his production company, Jagged Films.  The flick is based on an idea Mick had and tells the story of a Rupert Murdoch-like mogul and a young journalist who is brought into the inner circle of his media empire.  No word yet on if Mick plans to take the part or when the film will go into production.
