Melissa McCarthy is undoubtedly a star on the rise.
Just a few short years ago she was an emerging actress on TV sitcom The Gilmore Girls then Mike & Molly.
If those hadn't won her enough fans, she followed that up with a standout performance as Megan in Bridesmaids.
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.
