- The top 60s pop group Cliff Richard and the Shadows "appear" in this film in puppet form, Portrayed as future versions of themselves. They perform two songs: an instrumental, and "Shooting Star."
- The first feature film to be shot using the Livingston Electronic Viewfinder Unit, also known as Add-a-Vision. This was basically an electronic viewfinder that could be used in conjunction with a Mitchell BNC Camera to take a television picture directly from the camera, enabling the staff of the entire unit to watch any scene being filmed on the television monitors.
