Working Title are known for their rom-coms. Some of them, usually starring Hugh Grant, have been the biggest British films of recent years. I Give It A Year is their first anti rom-com which boasts plenty of com but very little rom.

As everyone is so unlikeable you find yourself without anyone to root for. Writer-director Dan Mazer, who has written for Sacha Baron Cohen in his various screen incarnations, provides plenty of comedy but no reason for the audience to wish for a happy ending.

Rafe Spall and Rose Byrne are the couple, Josh and Nat, who meet and marry within a year. Nine months later they realise they’ve made a big mistake. But what to do – admit they were wrong and split up, or try to make a go of it?

The decision is clouded by the fact that both have potential partners waiting in the wings. Josh has old flame charity worker Chloe (Anna Farris) back in his life. Nat hooks up with American businessman Guy (Simon Baker, on leave from The Mentalist) who’s eager to combine business and pleasure.

Spall makes the most of his biggest film role to date and Byrne is attractively perplexed as his wife but it’s Stephen Merchant as Josh’s foot-in-mouth best man and Minnie Driver as Nat’s bitchy sister who get the best lines.
