This was a pilot for a proposed series, but due to the health problems of director Hal Ashby and Graham Chapman, the series never came to fruition.
Although known mostly for the legendary Graham Chapman acting under Hal Ashby's direction, young lead actors Chris Young and Gabrielle Anwar would go on to having pretty good movie careers.
When Chris Young auditioned to play Jake, the casting director said he was too handsome to play the part. He won them over, improvising his lines and making them laugh during the reading. The casting director then sent over his photograph to Graham Chapman who concluded he wasn't too good looking at all. He gave Chris the part.
American network CBS was briefly interested in producing the show due to the 1988 writers strike. But when the strike ended, the network lost interest.
The trailer presses the fact it's Graham Chapman from Monty Python as the premise looks a cross between Holy Grail, where Chapman played the title character, and Terry Gilliam's Time Bandits where a modern boy goes back to Medieval Times, joining with a warrior from that period.
