In the 1970s through the early 1990s, several feature-film compilations and television specials were produced, mostly centering on Bugs Bunny and/or Daffy Duck, with a mixture of new and old footage. In 1976, the Looney Tunes characters made their way into the amusement business when they became the mascots for the two Marriott's Great America theme parks (Gurnee and Santa Clara). After the Gurnee park was sold to Six Flags, they also claimed the rights to use the characters at the other Six Flags parks, which they continue to do presently. In 1988, several Looney Tunes characters appeared in cameo roles in Disney's film, Who Framed Roger Rabbit. The more notable cameos featured Bugs, Daffy, Porky, Tweety, Sylvester and Yosemite Sam. It is the only time in which Looney Tunes characters have shared screen time with their rivals at Disney (producers of the film)—particularly in the scenes where Bugs and Mickey Mouse are skydiving, and when Daffy and Donald Duck are performing their "Dueling Pianos" sequence.
