And the Oscar goes to... Ed Catmull?!

Actress Jessica Biel hosted the 81st Annual Science and Technical Oscars Saturday night, which honors the critical yet complicated side of movies most people just don't understand.

Catmull, president of Pixar Animation Studios, picked up the night's first—and only—Oscar statuette for his lifetime achievement in computer graphics. Pixar's WALL-E is up for this year's Oscar for Best Animated Feature. In its 23-year history, the studio has won 21 Academy Awards.

While not televised, excerpts from the evening will be played during the telecast of the 81st Academy Awards Feb. 22.

A reigning Hollywood hottie always hosts the Sci-Tech Oscars, with Biel following in the footsteps of Jessica Alba, Scarlett Johansson and Charlize Theron.
