 While the film is an homage to the 1930s and 40s Universal Monster  horror films, the inclusion of Mr. Hyde is an oddity, as he was  never one of the Universal Monster roster. Instead, the films based  on Hyde during that time were made for Universals rival MGM.  However, in 1953, Universal did feature the monster in the comedy  _Abbott and Costello Meet Dr. Jekyll and Mr. Hyde (1953)_ (qv).
