Pirates of the Caribbean Premiere London

Its a film about pirates right? So why does Johnny Depp look more like a Dick Tracy detective than a pirate in his choice of hat at the London premiere. Unlike Keira Knightley who had obviously hit the treasure, in her shimmering gold number. Close your eyes kids! Obviously worried about being out done, Johnny quickly slapped on a temporary tattoo in homage to his character Jack Sparrow. That's it Johnny now you look like a pirate.
