Pete Docter, director of Disney/Pixar's new animated movie Up, and producer Jonas Rivera told reporters in New York and Burbank, Calif., that the movie mixes tragedy and comedy, talking dogs and floating houses in a movie designed to touch the heart. Docter and Rivera screened the first 46 minutes of the movie to audiences at New York Comic Con and at Walt Disney Studios in Burbank, Calif., this week, and SCI FI Wire was there. Up tells the story of 78 year-old Carl Fredricksen (Ed Asner), who in his golden years, sets out on the adventure of a lifetime by tying thousands of helium balloons to his house.
