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.

It's easily one of the freshest, sharpest and most enjoyable films of this year.

True to its essence, the characters remain on the same line and manage to entertain the viewer, each highlighting their own distinctive qualities or touches.

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