Does your dog have superhuman powers like Underdog? Is he super cute? Is she super tricky? If so, enter them in the "Underdog Super Pet Contest" on Disney.com and you can win a trip to the world premiere with your dog, and have them appear in Walt Disney Pictures' movie Underdog, in theaters August 3.

To enter, go to www.disney.com/UnderdogContest and submit a video or photo of your dog doing something super - from looking super sharp to attempting a super trick or feat. The contest began on May 10 and will end on June 1, when ten videos and ten images will be chosen as finalists by the filmmakers on the basis of super creativity and uniqueness.

Movie fans everywhere will have the opportunity to visit the contest site and vote for the finalists between June 8-14, with the top two most popular recipients in each category winning a trip to the Underdog world premiere in Los Angeles, CA.

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.

Underdog was released August 3rd, 2007 and stars Jason Lee, Peter Dinklage, James Belushi, Patrick Warburton, Alex Neuberger, Taylor Momsen, John Slattery, Amy Adams. The film is directed by Frederik Du Chau.
