Set in Little Italy, executive-produced by Martin Scorsese, and “inspired by” a true story, The Wannabe is a solid but unexceptional addition to the growing canon of gangster movies whose mobsters aren’t glamorous, soulful antiheroes, but canny and unprincipled brutes. Not much is known about why the real Thomas and Rosemarie Uva chose to do something as risky and, not to put too fine a point on it, stupid as robbing mafia social clubs in Queens (the Daily News called them Bonnie and Clod). In last year’s Rob the Mob, Thomas is portrayed as being angry at the mob for having beaten his father when he was late with his payments on a business loan, but The Wannabe’s writer-director, Nick Sandow, shows him as motivated by a childlike obsession with the mafia in general, and John Gotti in particular. Desperate to be accepted into one of the families, this version of the man somehow convinces himself that robbing gangsters as they play cards is a good way to prove that he belongs. But then, thinking isn’t exactly his strong suit.
