Melissa McCarthy has made quite a name for herself in recent years by playing characters who aren't exactly glamorous.
McCarthy defies Hollywood's craving for overly slim actresses and offers a more real character potential with her plus-size figure.
She stood out as Megan in Bridesmaids and, though her role as Molly in TV sitcom Mike and Molly is more traditional, it demonstrates her comedic talent.
Her character in Identity Thief is Diana, a lost soul who finds comfort in pulling off whatever rort she can get away with. She finds it quite easy to steal identities and run up huge credit card debts while totally indulging herself. It is fun and she never has to confront those she is hurting.
That is until she assumes the identity of mild-mannered Sandy Patterson (Jason Bateman), a hard-working husband and father.
