Even among Disney and Pixar films, there are few that bring the feels like Up. It has adventure to draw in the kids and love, loss, and rebirth to pull on the heartstrings of even the most cynical among us.

The film broke new ground for Disney and Pixar, both in terms of animation technology — it was the first film produced by Pixar to be shown in 3D — and commercial success. The movie went on to be nominated for Oscars in the “best animated feature” and “best picture” categories, an Academy Awards first.

Up celebrates its 5th anniversary today, so in the spirit of adventure, here’s some trivia behind Russell and Carl’s South American escapade.

1. Charles Muntz was named after an actual enemy of Walt Disney. Up’s villain Charles Muntz was named after Walt Disney’s real-life archenemy, Universal Pictures executive Charles Mintz. Mintz stole Disney’s production rights to “Oswald the Lucky Rabbit” in 1928. This lead Disney to create Mickey Mouse and quickly surpass Universal in animation popularity.

2. Carl’s grape soda button is a subtle nod to Buzz Lightyear. The grape soda button that Carl wears is a nod to the grape soda from the commercial for Buzz Lightyear in Toy Story.

It also happens to bear a striking resemblance to the retro soda, Nu Grape.

3. Dug was based on Disney’s original guide dog. Dug is loosely based on Mickey’s pet dog, Pluto. Specifically his color scheme, black nose and stiffened body when he’s locked on a tracking scent.
