In addition to a trip to the world premiere, an unlimited number of entries will appear in the film's end credits, allowing selected participants to see his or her dog in a movie theater on the big screen.

"It's a special opportunity to give the public a chance to own a piece of the film. This contest with Disney.com takes advantage of what the Internet has to offer - it empowers families to submit user-generated content that can be part of a collective shared experience," said Jim Gallagher, President of Marketing at Walt Disney Studios Marketing. "There's no better payoff than to be surprised at the end of the movie and see your favorite four-legged friend on the big screen."

In conjunction with the launch of contest voting, Disney.com will debut the Underdog payoff trailer online, which will also be in theaters with Pirates of the Caribbean: At World's End on May 25. At Disney.com fans will be able to visit the official Underdog Channel in Disney XD, a highly interactive broadband experience within the new Disney.com. They will be able to vote for their favorite contest finalists, watch the new trailer, play games, and chat with pre-set Underdog-themed phrases such as "There's no need to fear! Underdog is here!" Disney XD members who are fans of "man's best friend" can also leave special Underdog virtual stickers on their friends' channels.

"There's no need to fear. Underdog is here!" The superhero canine with a gift for rhyme returns in an all new live-action re-imagination of the classic cartoon, Underdog.

After an accident in the mysterious lab of maniacal scientist Dr. Simon Barsinister (PETER DINKLAGE), an ordinary beagle unexpectedly finds himself with unimaginable powers and the ability to speak. Armed with a fetching superhero costume, Underdog (voiced by comedian JASON LEE) vows to protect the beleaguered citizens of Capitol City and, in particular, one beautiful spaniel named Polly Purebread (voiced by Academy Award nominee AMY ADAMS). When a sinister plot by Barsinister and his overgrown henchman Cad (PATRICK WARBURTON) threatens to destroy Capitol City only Underdog can save the day.

Underdog stars Jim Belushi, Peter Dinklage, Alex Neuberger, Taylor Momsen with Amy Adams and Jason Lee as the voice of Underdog. Utilizing state-of-the-art CGI special effects mixed with live-action, Underdog flies into theaters in summer 2007.
