Bill & Ted's Excellent Adventures follows Bill and Ted as they continue their time travel adventures while being guided by Rufus to their destiny as the Two Great Ones whose music will bring about universal peace. Aired on CBS, the first season had the benefit of Alex Winter, Keanu Reeves, and George Carlin reprising their roles from the film. However, for the second season, the shows went through many production changes, switched to Fox Kids, and the two leads from the yet-to-air live action series took over for the voices of Bill and Ted.
