Monty Python and the Holy Grail is a 1975 British comedy film written and performed by the comedy group Monty Python (Graham Chapman, John Cleese, Terry Gilliam, Eric Idle, Terry Jones and Michael Palin), and directed by Gilliam and Jones. It was conceived during the gap between the third and fourth series of their popular BBC television programme Monty Python's Flying Circus.
