Boris Karloff had been Universal's original choice for the role as the Invisible Man. Karloff was said to have turned it down because he would not be seen on screen. In reality a quarrel with director James Whale broke up their relationship, and the director decided he wanted someone with more of an "intellectual" voice and Karloff's marked lisp had also become an issue. Whale selected Claude Rains after accidentally hearing Rains' screen test being played in another room. Until this film, Rains had primarily been a stage actor. Although he had appeared in one silent movie, Build Thy House (1920), this was his first sound film.
Man in Pub:
Did you hear about Mrs. Mason's little Willy? Sent him to school and found him buried ten-foot deep in a snow drift.
Man in Pub # 2: How did they get him out?
Man in Pub: Brought the fire engine 'round, put the hose pipe in, pumped it backwards and sucked him out.
A British Police station has the American words 'Police Department' spelled out on the door.
The opening credits appear out of thin air.
When the film was released to home video, Universal Studios replaced a snippet of music heard on the radio when Dr. Kemp is reading a newspaper in his house, and the Invisible Man enters through a set of French doors. Universal was unable to secure the rights for the original music and replaced it, covering the original sound effects (the sound of the newspaper and the door latch) in the process.
