WHAT'S IT ABOUT? Disillusioned furniture salesman with the luck of a squashed ant, attempts to give his view of the 'American Dream' by bombing the White House.

ANY GOOD? Enthralling, claustrophobic drama based on true events from 1974. Sean Penn is superb. Again.

DON'T SAY: "Ooh, this film is well like Taxi Driver, innit."

DO SAY: "Why Sir, I must confess this is a most stark account of modern American ideology, delivering chilling synonymy with the 9/11 disaster and eye-opening social commentary. Ahem."

EXTRAS: A profile on the film's inspiration joins the usual offerings.
