Star Wars actor Ralph Brown played identical characters in both Wayne's World 2 and a completely unconnected movie from five years earlier. British actor Ralph Brown started out working in London's legendary Scala cinema before he landed a career making role as Danny the drug dealer in 1987's Withnail & I. The classic comedy starred Saltburn's Richard E. Grant as Withnail, and Doctor Who's Paul McGann as "I", and is still a beloved cult classic to this day. Five years later, Ralph Brown was cast in Mike Myers and Dana Carvey's sequel to their SNL spinoff movie, Wayne's World.
