Son of stuntman Evel Knievel is suing Disney over a character in the film <em>Toy Story 4</em>. A federal trademark infringement lawsuit filed in Las Vegas this week accuses the company of improperly basing the character Duke Caboom from the 2019 movie on Knievel, whose famous stunts included motorcycle jumps over the Caesars Palace fountain in Las Vegas and a row of buses at Wembley Stadium in London, and a rocket shot into Snake River Canyon in Idaho. The lawsuit, filed by Las Vegas-based K and K Promotions, accuses Disney-owned Pixar of intentionally modeling the Caboom character, voiced by Keanu Reeves, after Knievel — although Knievel’s name is never mentioned. Son Kelly Knievel, head of K and K, has had publicity rights to Evel Knievel's name since 1998, according to the court filing. Speaking on Thursday, he said the filmmakers never sought permission to use his father's likeness. The Walt Disney Co, in a statement from corporate spokesman Jeffrey R Epstein, said it will defend itself vigorously against what it called Knievel's meritless claims. Knievel is seeking unspecified damages totaling more than $300,000 (Dh1.1 million) on allegations that also include false endorsement and unjust enrichment. The Caboom character is described by Disney Pixar as a 1970s motorcycle-riding toy based on “Canada’s greatest stuntman”, according to the lawsuit. Photos in the court filing put Caboom side-by-side with Knievel, who became an American icon after his near-fatal 1967 Caesars Palace crash. An Evel Knievel Stunt Cycle toy released in 1973 featured a Knievel action figure clad in a white helmet and jumpsuit with red, white and blue embellishments on a motorcycle propelled with a wind-up device. In vivid descriptions of the movie, the lawsuit notes the Caboom character is a 1970s-era daredevil clad in a white jumpsuit and helmet with Canadian insignia and a “Duke Caboom Stunt Cycle.” A propelled toy was marketed in conjunction with the movie, Knievel's attorneys note, and the Caboom character became part of a McDonald’s Happy Meal promotion. Consumers and film reviewers “universally caught on to the connection,” the lawsuit claims, while the movie company and Reeves avoided making any public association, connection or comparison “even if directly asked”. “Evel Knievel did not thrill millions around the world, break his bones and spill his blood just so Disney could make a bunch of money,” Kelly Knievel said in a statement announcing the lawsuit. Knievel was seriously injured many times during more than 75 motorcycle jumps. However, he died in 2007 at the age of 69 in Florida of lung disease, not in a crash.
