Filming on such a prestigious show as Sherlock must come with its fair share of stress – after all, millions of eager fans have been waiting nearly two years for the next instalment. It's a big responsibility.
So perhaps its no surprise that when they're not in front of the cameras, stars Benedict Cumberbatch and Martin Freeman like to unwind by slipping into something more comfortable.
Benedict, it seems, goes for broke and gets into his dressing gown, while Martin, as we might imagine, is very happy with a cosy cardigan and a mug of tea. And if he really wants to kick back and relax, he has been known to slip on a pair of fetching checked shorts.
See below for the photographic evidence from the set of Sherlock series three – and treat yourselves to a bonus shot of Mark Gatiss in a lovely pink jumper. It's on us.
