This unaired pilot was considered lost until Pepito Pérez's widow notified CBS that she owned the sole copy. It had been given to Pepito by Desi Arnaz and Lucille Ball as a show of gratitude for his friendship.
Before shooting the pilot, the characters' original last name, Lopez, was changed to Ricardo to avoid confusion with Vincent Lopez.
When the film was found, the opening and first few seconds of the pilot were damaged beyond repair. This scene was reconstructed for DVD in 2002 with a re-recorded narration by Bob LeMond, 50 years after he originally recorded it.
Bob LeMond was also the narrator on Lucille Ball's radio show "My Favorite Husband" on which this series was based.
