If... is a cult film by English director Lindsay Anderson. In the film, students at an English public school revolt bloodily against the establishment around them.
If... is a political comic strip which appear in the UK broadsheet newspaper The Guardian.
It is drawn by Steve Bell. It sharply satirises current politics. Shortly after it was revealed that John Major tucked his shirt into his underpants (by someone on a plane who saw him lean forward), Bell began drawing the then Prime Minister as Superman, with underpants on the outside of the trousers of his suit.
