In "The Demon in the Mattress" has many connections with the film "The Exorcist" such as the Muriel spinning her head, puking on Eustace, performing an exorcism, and the spirit transferring from Muriel to Eustace. All the like in the 1973 film.

Cousin Fred in "Freaky Fred", is based on the 'Sweeney Todd (Character)' - the Demon Barber of Fleet Street.
