Keira Knightley and Sam Worthington are a couple in trouble, thanks to Eva Mendes.
The first trailer for Last Night has popped up - apologies for the rubbish quality, but the film doesn't have a distribution deal yet.
It's the debut feature from Massy Tadjedin, the Iranian-American who scripted The Jacket, and she's working with that film's leading lady once more.
Keira Knightley stars as a woman suspicious of her husband Sam Worthington's behaviour around co-worker Eva Mendes. When Sam 'n' Eva go away on a business trip, Keira bumps into dashing ex-boyfriend Guillaume Canet, leading her into temptation.
