TransformersFROM MTV MOVIES: The killer MTV Movie Awards updates are coming fast these days. Earlier this week, we dropped a bomb about the "New Moon" cast presenting an exclusive clip from their upcoming "Twilight" sequel during the live broadcast. Now we can reveal that during the show, viewers will get an exclusive sneak peek at two summer blockbusters: "Harry Potter and the Half-Blood Prince" and "Transformers: Revenge of the Fallen."

Daniel Radcliffe, Emma Watson and Rupert Grint will present (via telecast from England) a never-before-seen clip from "Half-Blood Prince," the sixth movie adaptation of the J.K. Rowling boy-wizard book series. Megan Fox and director Michael Bay will be on-hand to show off a fresh clip from "Revenge of the Fallen," the sequel to the 2007 box office smash about shape-shifting robots.
