Monty Python's Big Red Book

Monty Python's Flying Circus was a highly influential comedy television series that was broadcast by the BBC on Earth between 1969 and 1974. It also spawned a series of motion pictures and books. One of these books, Monty Python's Big Red Book, would still be in print in the 51st century and is one of the many volumes stored in the planet known as The Library. (DW: Silence in the Library)

Behind the scenes
Monty Python alumnus John Cleese made a cameo appearance in City of Death and his name, along with that of fellow Pythons Eric Idle and Michael Palin, has frequently been cited as potential popular candidates for the role of The Doctor. Monty Python contributor Douglas Adams would later become story editor for Doctor Who and write several serials, including City of Death, before achieving fame for The Hitchhiker's Guide to the Galaxy.
