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 terrific literary drama and character piece that shows how the process of creating art can be seen differently by those doing it and those looking at it from the outside.

One of the most extraordinary films you will see this year. Take that as you want.

By the time the dramatic fireworks start popping off, each one feels earned.
