Disney/Pixar has released a new onesheet for Up, its upcoming 3-D animated comedy adventure, about 78-year-old balloon salesman Carl Fredricksen, who finally fulfills his lifelong dream of a great adventure when he ties thousands of balloons to his house and flies away to the wilds of South America. View it after the jump.

Carl discovers all too late that his biggest nightmare has stowed away on the trip: an overly optimistic 9-year-old Wilderness Explorer named Russell.

Up features the voices of Ed Asner, Christopher Plummer, John Ratzenberger, Delroy Lindo and Jordan Nagai.

The film, from Academy Award-nominated director Pete Docter (Monsters, Inc.), will be presented in Disney Digital 3-D in select theaters and opens May 29.
