The working title of the film was The Man Who Lived Twice. Although reviews refer to the operation that character "Steve Rawley" undergoes as a lobotomy, the procedure is not referred to specifically in the film. Man in the Dark was the first Columbia production to use the 3-D format, which, according to a March 1953 Variety news item, was developed secretly in the studio lab. The news item further noted that the process required "two cameras, but no mirrors" and was "simple, light and mobile." Information in the copyright record indicates that Man in the Dark was released in sepia, but the print viewed was in standard format and black and white.
