Sandra Bullock, who is nominated for a Best Actress Oscar for The Blind Side, won two Razzies: Worst Actress (for the romantic comedy All About Steve) and Worst Screen Couple (with Bradley Cooper for All About Steve). Bullock delivered on a promise to actually show up at the ceremony and accept the Razzies in person, handing out copies of the All About Steve DVD to the audience. If she wins the Oscar Sunday night, she will be the first actor ever to win a Razzie and an Academy Award in the same weekend.

Transformers: Revenge of the Fallen earned three Razzies: for Worst Picture, Worst Director, and Worst Screenplay. The Jonas Brothers were collectively named Worst Actors for Jonas Brothers: The 3-D Concert Experience. Billy Ray Cyrus won Worst Supporting Actor for Hannah Montana: The Movie, while Sienna Miller took home Worst Supporting Actress for G.I. Joe: The Rise of Cobra.

Special anniversary awards were given to the 2000 John Travolta sci-fi film Battlefield Earth for Worst Picture of the Decade; Eddie Murphy for Worst Actor of the Decade; and Paris Hilton for Worst Actress of the Decade.
