Then end credit sequence features Batman doing the "Batusi", which he did in the pilot episode for the 1966 TV series. Catwoman also does her own "Catusi". The dance names are references to a popular dance of the 1960s, "The Watusi". The format of the sequence is also similar to the end sequences of many of the 60s beach movies starring Frankie Avalon and Annette Funicello, although the dances were performed by Buster Keaton and his go-go girlfriend, Bunny.
