While sitting in her hotel room, Laura watches TV while an automobile ad is being run. The salesman is Don Lamond. Don was close friends with director Edward Bernds as well as Moe Howard, and was a staple on Los Angeles television in the 1950s and 1960s.
Over the years, some sources have regarded this as a "lost" film. A 35mm RegalScope print is maintained by UCLA.
When the cab driver (Moe Howard) says; "I'm all by myself!", this was a "inside joke" with the film crew, because the Stooges were suddenly out of work at the time, and this was Moe Howard first attempt at acting on his own without the rest of the Stooges.
In the scene where Laura enters the train station (Los Angeles' Union Station) you overhear an announcement regarding a departing train. The announcer was none other than Paul Frees, as usual doing multiple voices in a given film.
20th Century-Fox used this low-budget film as a co-feature for its blockbuster release A Mosca da Cabeça Branca (1958) in the US. Fox did not put this into a television syndication package. The film has remained almost unseen in the US since its theatrical run.
Moe Howard: , of The Three Stooges fame, as a cab driver. Production assistant Norman Maurer was Moe's son-in-law, and director Edward Bernds was a longtime friend and had directed many Three Stooges shorts and several of their features. Moe found himself out of work after more than 25 years when Columbia Pictures closed its Shorts department with no notice early in 1958. Bernds offered Moe the cab driver part, and Moe in turn asked him to take on hire Maurer, who was trying to get a foothold in the film business. Bernds knew Maurer and considered him to be a talented artist, so he hired him as a sketch artists to help the special-effects department.
