We'll be selecting a winner at 8pm UK time tonight so get on with it. We'll then contact the winner to confirm details, so watch your e-mail tonight.
And if you don't have twitter, or you don't win, we'll give you another another chance to get in. Simply turn up at the premiere in cosplay tomorrow and the best dressed will also scoop some tickets. Rock up by 5pm in your Earth's Mightiest finest.
