Back in 1962, the 36-year-old Mel Brooks was watching an avant-garde film when an old man behind him wouldn’t stop with his grumpy and frustrated running commentary. Brooks turned this experience into his own short film, The Critic, in which he ad-libbed over some abstract animation; borscht belt meets the downtown art scene.
The result was a three-and-a-half-minute piece of genius that won the 1963 Academy Award.
