Tilda Swinton in Conversation With Doug Aitken "The thing that keeps me being a performer," Tilda Swinton says, "is my interest in society's obsession with identity." Swinton, who will appear in the upcoming Wes Anderson film, "The Grand Budapest Hotel," and is known for her roles in "I Am Love," "Michael Clayton" and "Adaptation," talks to the artist Doug Aitken about what drives her as an actress. She appeared in the 2007 Aitken film installation "Sleepwalkers." The interview is part of the Source, a series of candid video conversations with several dozen noteworthy figures about their creative process, currently on view in a custom pavilion at the Sundance Film Festival. Over the course of two weeks, T will exclusively present clips of nine of Aitken's conversations for the series - with Swinton, Liz Diller, Paolo Soleri, James Turrell, Theaster Gates, Aaron Koblin, Alice Waters, Liz Glynn and Beck. To see them, visit our project page for the Source, where we'll be rolling out the interviews one at a time.
