Thanks largely to its leading actors, ‘Sherlock’ has become hugely popular, and Martin and his co-star, Benedict Cumberbatch, are often trailed by fans hoping to catch a glimpse of them.
Speaking to the Independent On Sunday, Martin explains: “When we're [filming at] our stand-in for Baker Street, it is hard to do your job, and I don't love it. I don't love it."
While fans don’t shout at the stars, the constant applauding between takes can be somewhat distracting for the cast.
“There's such a heightened sense of excitement, so every time we come out there's applauding - and it's like, 'No, can you n-' Or, if we do anything - 'Cut!' - applause... It's like, 'No, this isn't a gig...'
"Of course you want to be gracious with it and I obviously very much appreciate, as do we all, the fact that people love it… but also, yeah, it doesn't make you doing your job any easier."
Martin and Benedict are currently busy filming new episodes of ‘Sherlock’, and the show is due to return to TV screens with a 2015 Christmas special.
Plenty of fans who have attended filming have shared their snaps on Twitter, adding the hashtag ‘#Setlock’, as has the show’s location manager, Jeremy DeCoursey.
A teaser pic for the upcoming episode was released in November 2014, and it appears to hint that the detective duo could even be doing some time-travelling.
