If you thought Ryan Reynolds was nothing more than the go-to guy for handsome leads in rom-coms and blockbusters, think again.

In his new film, The Voices, Reynolds plays a disturbed man who thinks his cat is telling him to become a serial killer – obviously. Coincidently, he also killed in his outfit at the film's official screening at London's swanky Sundance festival this weekend.

Rocking a kind of 'super-cool university professor' vibe, the star kept to brown tones, starting with a cracking pair of boots, followed by some smart chinos, a slouchy grey cardigan and a neat polka-dot tie. He then finished the whole thing off with a smart grey dress coat and rakish beard. Top marks, Reynolds.
