Sneaky Pete is one of my favorites on amazon.

Premise (from wikipedia):

Sneaky Pete follows Marius, a con man who gets out of prison only to find himself hunted by the vicious gangster he once robbed. With nowhere else to turn, Marius takes cover from his past by assuming the identity of his cellmate, Pete and then "reunites" with Pete's estranged family — who have no reason to suspect he is not their long-lost loved one.
