 Filmed on 7 March 1998 at the Wheeler Opera House in Colorado as part of The US Comedy Arts Festival, it featured the five Pythons in an interview with host Robert Klein.
 The late Graham Chapman was also allegedly in attendance as his "ashes" were brought out in an urn, only to be knocked over by Terry Gilliam.

Lost in La Mancha is a 2002 documentary film about Terry Gilliam's unfinished film "The Man Who Killed Don Quixote", a film adaptation of the novel "Don Quixote" by Miguel de Cervantes.
 It was shot in 2000 during Gilliam's first attempt to make the film with the purpose of being its making-of, but Gilliam's failure in making the movie led it to be retitled "Lost in la Mancha" and to be released independently.
Derrick O'Connor (born 3 January 1941) is an Irish character actor, best known for his performance as Pieter Vorstedt in "Lethal Weapon 2".
 He is also known for his roles in Terry Gilliam films, and was a member of the Royal Shakespeare Company.
 Gilliam, who has directed O'Connor in three films, has noted in his audio commentaries that O'Connor seems to have a habit of taking away most of his dialogue in favour of physical character humor.
 Notable examples include "Time Bandits", in which his characters' dialogue was resorted to simple grunts while the Maid Marian character "translated" for him and in "Brazil", in which O'Connor scrapped all of his character's dialogue and simply repeated the dialogue of Bob Hoskins' character.
