Rumer Willis stopped by The Late show with David Letterman Monday night to promote her new film, Sorority Row, a remake of the 1983 slasher flick The House on Sorority Row in which six sisters scheme to shame a cheating boyfriend by staging a death.

In Mike Judge's Extract, Mila Kunis plays the comely new co-worker of Jason Bateman’s factory manager, who tempts him into an extramarital affair.

Diane Kruger appeared on The Late Show with David Letterman last night to promote Quentin Tarantino’s Inglourious Basterds, in which she stars with Brad Pitt.

In the family comedy Shorts, a collection of interwoven vignettes, the appearance of a mysterious rainbow-colored rock with the ability to grant wishes disrupts life in a suburban community.

In The Time Traveler’s Wife, based on Audrey Niffeneger’s novel of the same name, Rachel McAdams plays the long-suffering spouse of a Chicago librarian (Eric Bana) with a very unusual genetic disorder that renders him prone to chronological displacement.
