THE ADVENTURES OF DON QUICK (1970)
The Adventures of Don Quick is a science fiction comedy television series broadcast from October–December 1970, on ITV. Starring Ian Hendry and Ronald Lacey, six 50 minute episodes were made, shown in a 60 minute time slot.
Based on the characters of Don Quixote, astronaut Captain Don Quick and Sergeant Sam Czopanser (i.e. "Sancho Panza") are members of the Intergalactic Maintenance Squad. On each planet they visit, Quick attempts to right imaginary wrongs, often upsetting the inhabitants of whatever society he's in.
As of 2008, only the first episode exists, the other five are now missing. A technologically impressive 30 foot model spaceship was built in the studio for the series. However the first three episodes in a primetime slot failed to draw the required ratings so the last three were in a much later slot before the show was cancelled.
