It's funny, it's tense, it features two great performances from two actors and the director expertly creates a web of odd tension where you actually don't know what is happening for the majority of the run time.

Blistering performances.

The film never slows down or bores, plunging from one harrowing sequence to the next.

It's simply great fun, a winsome film and an occasionally over-the-top luxury fantasy that never flags.
