good back-story, and good acting

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.

A film of deceptively outspoken contemporary relevance, this is cinema at its most alert, alarming and alive.

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