Remember when Jim Carrey used to be funny? The Mask, Ace Ventura, hell, even Dumb and Dumber… You giggled. You snorted. You unceremoniously emptied your bowels – whatever – you definitely laughed. But after a couple of solid tankings at the box office (Fun With Dick and Jane, Number 23), things didn’t look so bright for Mr Carrey.

Until now. Based on the novel of the same name by Danny Wallace, Yes Man sees Jim returning to form – and actually making us laugh. The premise is simple: our man Jim says yes to absolutely everything, resulting in some hilarious hijinks, including bungee jumping, chain-drinking Red Bull and… learning Korean. It’s funnier than it sounds – click on the clip above to find out for yourself.

And when you’re done with that, check out his new co-star, the ludicrously named but undoubtedly very cute Zooey Deschanel.
