Some footage from the film that was shown at the CES expo in Las Vegas and it has leaked online, so click below to watch a brief clip from the film.

From the Academy Award-nominated team of director Pete Docter (Monsters Inc.) and co-director Bob Peterson comes Up, a comedic adventure taking off (and lifting spirits) in summer 2009. Carl Fredricksen spent his entire life dreaming of exploring the globe and experiencing life to its fullest. But at age 78, life seems to have passed him by, until a twist of fate (and a persistent 8-year old Junior Wilderness Explorer named Russell) gives him a new lease on life. Up takes audiences on a thrilling journey where the unlikely pair encounter wild terrain, unexpected villains and jungle creatures. When seeking adventure next summer - look Up.
