It's Not Easy Being Green...Unless You're King

Yes, Shrek is back, and with the whole crew in "Shrek the Third." In this new installment, Shrek's new father-in-law, King Harold, has become ill. The duties of king and queen of Far, Far Away have now passed to Shrek and Fiona, however, they are perfectly content living in Shrek's swamp, and feel no desire to rule. In order to get out of this predicament they must seek out the heir to the kingdom, Artie(voiced by Justin Timberlake), a young rebellious boy, who they must convince to become king. To do so, Shrek rounds up Donkey and Puss in Boots to help him out, while Fiona and her band of princesses get together to stop Prince Charming from seizing the throne while Shrek is away.
"Shrek the Third" adds new voices such as Justin Timberlake as Artie, Fiona's teenage cousin, who is one of the stars in this addition. New voices also include Eric Idle (Monty Python and "Spamalot") as Merlin, John Krasinski (The Office) as Lancelot, Ian McShane (Deadwood) as Captain Hook, the band of Princesses include Cheri Oteri (SNL) as Sleeping Beauty, Amy Poehler (Mean Girls) as Snow White, Maya Rudolph (SNL) as Rapunzel and Amy Sedaris (Strangers With Candy) as Cinderella. Larry King also reprises his character, Doris, the Ugly Stepsister, and even Regis Philbin is the voice of Mabel, the other Ugly Stepsister.
"Shrek the Third" is set to come out May 18, 2007.
