About the movie:

"With its central theme of sexual jealousy and a willingness to probe the sometimes seedy and pathetic nature of desire - best exemplified in a scene where Portman strips for Owen - this is demanding stuff.

"However, there's also a surprising amount of humour between the heavy confrontations, like Anna's initial meeting with Dan who mistakenly believes her to be a sex fiend he encountered in an internet chatroom.

"All the performances are strong, with Portman especially fearless and Owen simply fearsome as a man driven by his base instincts." BBC
