Claire Danes plays it dangerously low in a black backless dress at the Los Angeles premiere of Stardust on Sunday. The Matthew Vaughn-directed fantasy film is based on the novella by Neil Gaiman. In the film, Danes play Yvaine, a star that transforms into a striking girl. Not too far behind on the red carpet: Claires British beau Hugh Dancy. Stardust is in theaters nationwide on Friday, August 10.
