To all those who have watched it: I hope you enjoyed it as much as I do.

This is a must-see and one of the best documentaries - and films - of this year.

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