Official Oscars Trailer: Billy Crystal Hunted by Josh Duhamel, Megan Fox (Video)

Robin Williams, William Fichtner and Vinnie Jones also star in the 2012 Oscars promo

We already know who's going to host the 2012 Oscars, but a newly released trailer from the Academy finds "Transformers" co-stars Josh Duhamel and Megan Fox sent off to track him down.

An exec — played by "Prison Break" and recent "Entourage" guest star William Fichtner — sends the pair off on a global adventure to find the "off the grid" legend. And after encounters with a bartender played by Vinnie Jones and a … hairy swamp guy played by Robin Williams, they meet "the one they call 'The Host.'"
