Im looking for the title of a move about a family of Bank robbers... I think it is set in the 20's but it is not the Newton Boys movie. It is about a Mother and her sons that rob banks.

Perhaps Public Enemies (http://www.imdb.com/title/tt0114202/)

No, I saw it quite a few years ago. Thanks though

Maybe one of Ma Barker's other films: Ma Barker (Character) (http://www.imdb.com/character/ch0034551/)
