In the video, Leto -- who has already scored best supporting actor Independent Spirit, Critics' Choice, Golden Globe and Screen Actors Guild award nominations and won the New York and Los Angeles film critics' corresponding prize -- discusses what drew him to playing the character, what she taught him about himself, how he has come to admire her and what he went through to bring her to life. Among other things, he shed 40 pounds, waxed his body, altered his voice pitch and spoke with a dialect.

The video also features Leto's costars Matthew McConaughey and Jennifer Garner describing their experience of working on the film with the actor -- whom, they say, they only ever met as Rayon, and who remained in character throughout the indie's shoot.
