Fox, Williams appear in Oscars trailer BEVERLY HILLS, Calif., Jan. 6 (UPI) -- Hollywood's Academy of Motion Picture Arts and Sciences has produced its trailer for the 84th Academy Awards in conjunction with the Funny or Die Web site. The clip features host Billy Crystal and celebrity cameo appearances by Robin Williams, Josh Duhamel, Megan Fox, William Fichtner and Vinnie Jones. "We wanted to try something a little bit different this year instead of a traditional, clip-based piece," Academy Chief Marketing Officer Christina Kounelias said in a statement Thursday. The trailer has a fun twist that conveys how excited everyone is to have Billy back. "Our team had a great time working with the academy and joining forces with Billy again," said Mike Farah, Funny or Die's president of production. We think the trailer really speaks to the excitement around this year's Oscars, and Funny or Die was honored to be a part of it. The trailer will have a one-month run in more than 2,000 theaters beginning Friday and can be viewed online at Oscars.org/trailer. Academy Awards for outstanding film achievements of 2011 will be presented Feb. 26 at the Kodak Theatre at Hollywood & Highland Center, and televised live by the ABC Television Network. This will mark Crystal's ninth turn as host of the Academy Awards.
