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. The original music and missing sound effects were restored to the 2012 blu-ray audio.
