IAN McEwan's novels are recognised as being difficult to translate to the screen.

But Notting Hill director Roger Michell's film builds up an atmosphere of worry and unease that turns this drama-come-stalker-thriller into something special.

The opening images of an idyllic summer's day in the countryside are shattered by a runaway hot air balloon with a child trapped inside the basket. Passers-by rush to help and bring the balloon back down to earth. Despite their efforts, one man dies in the horrific incident.

The effect on the other rescuers, notably Craig's college lecturer Joe, is devastating and long-lasting. His relationship with sculptor girlfriend Claire (Samantha Morton) goes downhill, much to the concern of their friends (Bill Nighy and Susan Lynch).

Joe becomes increasingly agitated which is hardly surprising as another of the would-be balloon rescuers Jed (Ryhs Ifans) appears to be obsessed with him. He not only watches him day and night but attempts to talk to him, wanting Joe to admit that he loves him.

Craig skilfully charts a man cracking up under the strain, while Ifans - both in this and the upcoming period piece Vanity Fair - shows there's more to him than playing comedy in grubby underpants.
