DVD: Last Night (12)

An understated examination of monogamy, Last Night sees Keira Knightly put in a strong (and relatively un-pouting) performance as Joanna, a British writer living in New York.

While her husband is dispatched on business with an alluring colleague (Eva Mendes), Joanna is accidentally reunited with an old flame. As the separated couple deal with temptation, they face up to bigger questions – not all of which are resolved. A pleasing, if unexceptional, way to pass an evening.
