Armie Hammer stopped by the Tonight Show last night to help premiere the first trailer for The Lone Ranger, his upcoming movie with Johnny Depp. Gore Verbinski directed the film, which stars Hammer as the title character and Depp as his trusty sidekick, Tonto. The teaser is packed with scheming robber barons, train-chasing bandits and gun slinging, plus one doozy of a tag line whispered by Depp with foreboding gravitas: "There come a time, kemosabe when good men must wear mask." The Lone Ranger is set to hit theaters next summer.
