As the Josh Hamilton free agency sweepstakes shift in to high gear this week, there is also news about the movie that's slated to be made about his life.According to Deadline.com, Relativity Media has signed a deal to produce the movie about the Texas Rangers outfielder's life in baseball, his struggles with addiction and how his faith has helped him persevere.As previously reported, Casey Affleck is slated to write and direct the film. It's not clear if Affleck (whose only other directorial credit is the quasi documentary I'm Still Here starring his pal Joaquin Phoenix) intends to play Hamilton. There's also no word on how closely Hamilton will be involved in the film, or how it will change depending on which team he ends up playing for. Rangers GM Jon Daniels says Hamilton's future with or without the club is coming into clearer focus.Relativity Media, according to its website, "has produced, distributed, and/or structured financing for more than 200 motion pictures," including Tower Heist, Bridesmaids, Limitless, Hop, Cowboys & Aliens, and The Social Network. It also operates a fairly new sports management group called Relativity Sports, whose clients include newly crowned American League MVP Miguel Cabrera, Arizona Cardinals wide receiver Larry Fitzgerald and New York Knicks forward Amar'e Stoudemire, among others. Hamilton is not currently listed as one of the agency's clients.
