TAKE a guess at the A-list star hidden under all those prosthetics. Unbelievably this is Tom Hardy.

The Taboo actor, 40, posted on Instagram this transformation to play crime boss Al Capone.

He recreated a famous mugshot for upcoming film Fonzo, which follows Capone in his final years struggling with dementia from neurosyphilis.

Still, that jawline is a clue that Tom is under there.
