Trivia

Special Guests in the Blackmail sketch included Stephen Fry, Lee Mack, Bill Bailey, Noel Fielding, Matt Lucas, Warwick Davis, Simon Pegg, David Walliams, Eddie Izzard (who also appears as a celebrity "Bruce" in the last show), and Mike Myers. Astronomy Professors Brian Cox and Stephen Hawking also appeared, explaining the mistakes in the "Galaxy Song" lyrics.

The show was created because they owed 800,000 pounds sterling to Mark Forstater, the producer of Monty Python and the Holy Grail (1975), over legal fees and back royalties for their stage show "Spamalot!" The show was supposed to be for only one night, on July 1, 2014, but high demand for tickets turned the show into a 10-night event. Enough money was made that not only were they able to pay Forstater, but each surviving major Python actor was also able to pocket 2,200,000 pounds sterling.

The Blackmail sketch included a different special guest each night of the live production. July 1: Stephen Fry; July 2: Lee Mack; July 3: Bill Bailey; July 4: Noel Fielding; July 5: Matt Lucas; July 15: Warwick Davis; July 16: Simon Pegg; July 18: David Walliams; July 19: Eddie Izzard; July 20: Mike Myers. The performance was filmed on July 20, so only the Mike Myers version appears in this film.

The first show sold out in 45 seconds.

Robin Williams was supposed to be the celebrity guest on Blackmail for the final night, but declined due to "severe depression", which would take his life the next month. The video release was dedicated to him.
