25 best school movies ever

If… (1968)

Receiving an X certification upon its release due to its disturbing portrayal of public school brutality in the 60s, this oddly titled film follows the struggle of three non-conforming students who struggle against the oppression of a bunch of nasty prefects called the whips.

Surreal (flicking between black-and-white and colour sequences due to time constraints on location) and often violent, it's regarded as one of the best British-made films of all time.
