I once read somewhere that the Monty Python actors had played with the idea of making a sequel to "Holy Grail", where they would be old, arthritic knights who had to make a last pilgrimage to the Holy Land. Graham Chapman was dead by the time they had the idea, but they were going to make that a plot element--he'd be a dead member of the party, who was just a holy relic, a box full of horrible bones that they had to lug around with them. And they could have him be a talking character, because they still had hours of recordings of Graham Chapman's voice. I wish they'd done it, just for the queasy laughs in that concept.

Anyhow, it never got made, but I kind of wish the SyFy Channel's description was that movie.
