Advertised as "The World's First Live Movie", this movie was broadcast in select theaters as it was being filmed. A single camera was used for filming.
The scene when Woody can't remember the hotel phone number was partly ad-libbed, as another actor was late in appearing.
On the day filming was about to start, the Waterloo and Westminster bridges were closed after a WWII bomb was found there. As those locations were originally going to be in the film, the crew had to act quickly in order to find alternatives in time.
