Monty Python and the Holy Grail (1975) is a surrealist cult comedy that follows a hilariously incompetent King Arthur on his quest. Funded by legendary rock bands like Pink Floyd and Genesis due to a low budget, the film features iconic, improvised scenes like the coconut-riding knights and the Killer Rabbit. The film abruptly ends when modern police arrest the cast, breaking the fourth wall in a memorable conclusion. You can watch this classic film on platforms like IMDb .
