As fans of the annual MTV Movie Awards would expect, Sunday's show featured awards for the latest "Twilight" movie (two this year), buzzy moments (Christian Bale teared up onstage following a video montage with the late Heath Ledger), and musical performances (fun.'s "We Are Young" opened the show). As has become the tradition, awards night also marked the premiere of the trailer for a much-anticipated new film. This time, it was one of Emma Watson's first post-"Harry Potter" projects: "The Perks of Being a Wallflower." Logan Lerman ("Percy Jackson") and Ezra Miller ("We Need to Talk About Kevin") star alongside Watson as a trio of misfit high school students. The three become best friends coming of age in the movie based on the 1999 Stephen Chbosky novel of the same name. The book's not exactly kiddie fare; The American Library Association named it to its list of the 10 most frequently challenged titles as recently as 2009. The reasons given most often are that it's "anti-family, [features] drugs, homosexuality, offensive language, religious viewpoint, sexually explicit, suicide, unsuited to age group."

Watson, 22, explained her interest in the rated PG-13 project to MTV News last year. "Honestly, I had never read the book before, but a lot of my friends at Brown [University] were hugely into it, and when I told them I had this script, they were crazy excited," said the former Brown student, who has now transferred to Oxford University in her homeland of England. "I feel incredible about it. I feel like I've been waiting for 'Perks.' I was waiting for this story, for this script, for this moment, for these people to do it with me. I'm so glad I didn't do anything that I didn't care about." The former Hermione Granger also followed up the "Harry Potter" franchise with a supporting role as a costume designer in December's "My Week With Marilyn."
