Monty Python's Big Red Book

Behind the scenes
Monty Python's Big Red Book was one of the better-known books based upon the 1969-74 TV comedy series Monty Python's Flying Circus, which in turn spun off a number of (plotwise unrelated) feature films. The Doctor Who franchise has a number of connections to Python, most notably in Douglas Adams, a contributor and occasional bit player in the original series who wrote for and served as script editor for the series in the late 1970s, and John Cleese who had a cameo in DW: City of Death. At one point or another virtually all of the lead actors in Monty Python were rumoured to be in consideration to play the Doctor.
