"Shrek The Third" Teaser

Moviefone has the new teaser trailer for "Shrek The Third" (May 18). "Happily ever after," sadly for newlyweds Shrek and Princess Fiona, is not the end. In "Shrek the Third," King Harold of Far, Far Away falls ill, and Shrek recruits Donkey and Puss-In-Boots on a quest to unearth a rightful heir to the throne, as the surly green ogre doesn't aspire to vacate his cozy swamp for the crown. In the first "Shrek The Third" photo (above), Princess Fiona (center, voice of Cameron Diaz) joins a posse of fairy tale princesses with the likes of (from left) an obsessive-compulsive Cinderella (voice of Amy Sedaris), a fussy Snow White (voice of Amy Poehler), a pugnacious Rapunzel (voice of Maya Rudolph) and a narcoleptic Sleeping Beauty (voice of Cheri Oteri) to protect the kingdom from coup.
