The security guard talking to timmy about the patridge family is danny bonaduce who played on the partridge family show.
In the close-up of the driver's license, the word 'reverse' is misspelled.
Show creator Tim Doyle reports that Danny Bonaduce was great to work with and very generous for flying in and lending his talent and celebrity to a first-year show. Trying to get "the Duce" for his cameo as movie studio guard was a notion that only occurred to Doyle very late in the script process. The writers beefed up the part to include some "fourth wall" jokes and to make the whole thing more worth the actor's time.
This episode is actually based on an experience from the life of show creator Tim Doyle who entered a cereal box contest in the early '70s to win a walk-on role on the Monkees TV show. The Monkees never called but he learned a valuable lesson that show-biz is a tough racket and got a lot of joy out of all the day-dreaming of future stardom the contest had afforded him.
Show creator Tim Doyle reports that this episode was especially memorable for the fights he had with the studio while shooting it. By this point in the season Disney Television was complaining every week that the scripts submitted were too "ambitious" - meaning more expensive than they wanted to subsidize. The scripts had too many scenes, characters, locations - all of which would need to be dressed up to look like 1972. Plus this script in particular had a big guest star, stunts, moving cars, special effects and music the show would have to produce and license. The folks in Burbank wanted several big cuts. Doyle refused. Reportedly the Disney TV bosses even enlisted the episode's director to tell Doyle emphatically that this episode would be "impossible" to shoot in the allotted number of days. But Doyle held firm and somehow the episode was shot within the schedule, but going slightly over-budget as the show always did because of its cast size and period setting. As Doyle puts it, by standing firm he won nearly all of the many budget battles he had while producing this series. Yes, he won the battles Doyle insists - and got to make the show he wanted - but then ultimately lost the war when Disney and ABC declined to give him a second season.
