Armie Hammer was at CinemaCon in Las Vegas this week to promote his first big leading role in The Lone Ranger. We caught up with the actor just before he teamed up with his costar Johnny Depp for a Q&A about the film. Armie talked to us about the experience of shooting "in the middle of nowhere," the karaoke parties the cast and crew shared at night, and why the "bohemian" Johnny is unique from the other great actors he's worked with.
