La fiesta inolvidable

This film was improvised from a 56-page outline. Each scene was shot in sequence and built upon the previous scene. To aid in this experiment, the film's producers had a video-camera tube attached to the Panavision camera and connected to an Ampex studio videotape machine, allowing the actors and crew to review what they had just filmed. According to a contemporary article in Daily Variety this was one of the first productions to use a video camera in this matter. This eliminated the time and expense of developing the film and showing the "rushes" the following day. The cost of this new technology was $1100 per day, but director Blake Edwards said the system saved the production many times that amount by avoiding costly resets and re-shoots on following days.
