The plot centres on the pilgrim's failed attempts to gain entry to the castle by any means possible, and the lengths the lord will go to in order to stop him.
In one memorable scene once the assailant has gained entry the lord brandishes an aerosol can labelled "Knight-Rid" to stop the pilgrim in his tracks Further filming at Hever was planned for May 1984 as filmmaker Charles Wallace intended to expand the film using Beryl Reid to play Eric's mother, and another damsel in the cast.
Morecambe's death ensured that further scenes were not made, but the film was released in its original shorter form.
The film was released with the James Bond movie Octopussy and WarGames (see production company website movingimageco.com).
It was later shown on numerous cable TV channels and was released in 1994 on VHS at a time of resurgence in interest in the work of Morecambe and Wise, the BBC having screened a three (late expanded to five) part tribute to mark the tenth anniversary of his death.
