Kenneth Strickfaden created and maintained the laboratory equipment. Strickfaden recycled a number of the fancifully named machines he had created for the original Frankenstein for use in Bride , including the "Cosmic Ray Diffuser",  and the "Nebularium".  A lightning bolt generated by Strickfaden's equipment has become a stock scene, appearing in any number of films and television shows.  The man behind the film's special photographic effects was John P. Fulton , head of the special effects department at Universal Studios at the time.  Fulton and David S. Horsely created the homunculi over the course of two days by shooting the actors in full-size jars against black velvet and aligning them with the perspective of the on-set jars. The foreground film plate was rotoscoped and matted onto the rear plate. Diminutive actor Billy Barty is briefly visible from the back in the finished film as a homunculus infant in a high chair, but Whale cut the infant's reveal before the film's release. 
The Monster is Monster in My Pocket #13. He appears among the good monsters in the comic book (1991), the video game (1991), the animated special (1992), and the 2003 animated series. In the comics, he was relatively inarticulate, represented by hyphens between each syllable he spoke, but possessed of simple wisdom and strong morals . This characterization was essentially characterized in the video game, where he was a playable character, and his only line of dialogue in the cut scenes was "Yeah..." In the animated special, he was known as "Big Ed" and was essentially a comic simpleton.
