He calls The Panic Room his 'popcorn movie'. However, his idea of a popcorn movie is 'Straw Dogs meets Rear Window.' Salt, butter and a king-size mallet, please. With all the action confined to a four-storey 'Townstone' ('a cross between a Townhouse and a brownstone' says the estate agent, the similarity to 'tombstone' totally intentional) The Panic Room resembles Home Alone, as directed by the Marquis de Sade. But, the marquis would enjoy inflicting the film's reign of terror a whole lot more than Fincher, who finds directing an agonising experience. 'You're never able to do what you want, ever,' he insists. This is the guy who thought that Seven wasn't scary enough.
