Charles F. Muntz in Up
The 2009 Disney/Pixar movie Up introduced Charles F. Muntz (Christopher Plummer) as a famous explorer admired by Carl Fredricksen (Ed Asner) and his late wife, Ellie (Elie Docter) as children. But when Carl and his new friend Russell (Jordan Nagai) finally met Charles in person, they found out that the latter wasn’t the kindly old adventurer they were expecting.
In the film, Charles found the bones of a tropical bird in South America but the scientific community claimed they were fake. Insulted, Charles searched the South American wilderness for a live member of the same bird species. His obsession, however, made him a heartless man consumed by bitterness. Paranoid to the extreme, Charles was convinced that anyone who comes across him is after the bird. It’s even implied that he killed two explorers already, and was intending to do the same with Carl and Russell.
