Zoltan Krisko, who manages the estate of late Hungarian composer Gyorgy Vukan, is suing Marvel, Disney, FOX, Apple and Amazon, among others, for a copyright violation pertaining to the theme song to the 1990s X-Men: The Animated Series cartoon show.
Krisko claims those behind the fan-favorite cartoon stole the intro music Vukan composed for the Hungarian police comedy-thriller Linda, which aired from 1984-1991. As you can see from the two videos below, the similarities are pretty uncanny.
Krisko didn't learn of X-Men: The Animated Series until 2017 but claims those behind the series were friendly with Hungarian film professionals in the '80s, which would explain how they were exposed to the tune in the first place. As a result, Krisko is seeking financial compensation for Vukan's estate based on the profits the cartoon has made since it debuted in 1992.
Running for five seasons between 1992-1997 on Fox Kids, X-Men: The Animated Series is considered by many to be one of the best comic book-based cartoons, notable for its mature storytelling and complex characters. Among the many stories from the comics adapted for the series was "The Dark Phoenix Saga," which was recently brought back to the big screen as Dark Phoenix.
