The Lost Saucer was yet another of Sid & Marty Krofft Productions' Saturday morning series involving characters being whisked away to another land, and spending the entire length of the series (an entire season) trying in vain to get home. This time around, two androids named Fi and Fum (Ruth Buzzi and Jim Nabors) land their saucer on a residential street in modern-day (1975) Earth; they attract the attention of a young boy named Jerry and his babysitter, Alice, whom Fi and Fum invite aboard their saucer, and show them what their saucer can do. At the same time, Fi and Fum also attract the attention of police and fire departments, and in a panic, take off... with Jerry and Alice still on board.
Since the Lost Saucer had the ability to travel through time, each attempt to bring Jerry and Alice back home results in them landing back on Earth, either in the past or in the future.
This series provides examples of:
- Acting for Two: One episode has the saucer recalled to Fi and Fum's home planet, where their creators are also played by Ruth Buzzi and Jim Nabors in age makeup.
- Amnesia Episode: Almost all Krofft shows have them. This one involves Fum losing his memory bank, and an evil empress trying to use him to carry out her sinister plot.
- And Now For Something Completely Different: Averted with the series as a whole, but inverted, as some episodes actually took a swipe at social satire, such as the Lost Saucer landing in a future where obesity is embraced, and considered more desirable and attractive.
- Courtroom Episode: Inverted in the pilot episode, where Jerry and Alice are arrested and put on trial for not "wearing their numbers", as in that particular period in the future they visited, all people must wear outfits with numbers printed on them, and those numbers are their identification (no names, just numbers).
- Fantastic Comedy
- Flying Saucer: Obviously.
- Foreign Cuss Word: In the pilot, an angry Fi pushes a button on her tape deck, resulting in her gibbering indistinctly at Fum for his latest screw-up, while Fum tells her to be mindful of her language in front of the Dorse (who covers his ears with his paws).
- Laugh Track
- Mix and Match Critter: The Dorse is one.
- People in Rubber Suits: No Krofft show would be complete without 'em!
- Ridiculously Human Robots: Fi and Fum are actually robots... but look more like people wearing futuristic space outfits.
- Short Runner: Like most Krofft shows, this one lasted for one season (and 16 episodes).
- Team Pet: Fi and Fum's pet Dorse... a creature with the head of a small horse, and the body of a big shaggy dog.
- Timey-Wimey Ball: And how.
- Wave-Motion Gun: A low-powered, kid-show-friendly example: Most threats in the stories are dealt with by the use of a laser beam that emerges from Fum's right elbow. Holding off the threat long enough for Fum to charge and aim the laser is a frequent plot point.
