Cate Blanchett attended "The Hobbit: An Unexpected Journey" U.K. premiere today looking glamorous in a white Givenchy gown.

The dress featured a slit up her right leg, showing off her lean figure, and was open in the back.

The film centers on hobbit Bilbo Baggins (Martin Freeman) who joins the wizard Gandalf (Ian McKellen) and a band of dwarves on a treacherous quest to a distant mountain. Blanchett plays the elf Galadriel. It hits theaters on Dec. 14.

J.R.R. Tolkein, author of "The Hobbit" and the "Lord of the Rings" trilogly, described Galadriel as "the mightiest and fairest of all the Elves that remained in Middle-earth." We can see why Cate was chosen for the role so many years ago. She is timeless!
