If....

Everything About Fiction You Never Wanted to Know.

if.... is a 1968 film written by David Sherwin, directed by Lindsay Anderson, and starring Malcolm McDowell, in his film debut, as Mick Travis.

The film is set at a Boarding School, and is best known for the climactic sequence in which conflicts between the students and the school authorities escalate into outright warfare with automatic weapons.

Sherwin, Anderson, and McDowell collaborated on two further films, O Lucky Man! and Britannia Hospital; both also feature McDowell as a character named Mick Travis, but they do not constitute a series except in Broad Strokes.

Not to be confused with If..., a comic strip with one fewer periods in its title, or Shin Megami Tensei: if..., a game that shares many themes with this movie.
