Where can I watch The Wrestler in United States?

Frank Bass (Ed Asner) is an honest guy trying to make a living in the cut throat world of professional wrestling, and he's gonna make it work - even if he dies trying! But first - he'll have to strong-arm his way through all the mobsters, gamblers, promoters and fight fixers and help his past-his-prime wrestler once again win a championship belt. Features appearances from real-life legendary wrestlers and AWA superstars Verne Gagne, Rick Flair, Superstar Billy Graham, Dusty Rhodes, Dick the Bruiser, Ray Stevens, Dory Funk Jr., Ken Patera, Billy Robinson, Dan Gable, Eddie Graham, Dick Murdoch, Vincent J. McMahon, and more.
