What 1975 comedy film features knights who say 'Ni' and a killer rabbit?

The 1975 comedy featuring knights who say “Ni” and a killer rabbit is Monty Python and the Holy Grail.

The film sends King Arthur and his knights on a deliberately chaotic quest for the Holy Grail. Its medieval setting is constantly disrupted by modern jokes, abrupt editing, low-budget production tricks, and characters who treat absurdity as ordinary reality. The Knights Who Say “Ni!” demand a shrubbery, while the Rabbit of Caerbannog turns out to be a lethal guardian rather than a harmless woodland creature.

The killer rabbit scene is one of the film’s best-known comic reversals. After the rabbit kills several knights, Arthur’s group defeats it with the Holy Hand Grenade of Antioch, an intentionally grand religious relic presented with mock-serious ceremony. Other famous episodes include the Black Knight, the French castle taunts, and the coconuts used to imitate horses.

Monty Python members Terry Jones and Terry Gilliam shared directing duties. The film was released in 1975 and became one of the troupe’s defining works, helping establish its enduring reputation for surreal, quotable comedy.
