Benedict Cumberbatch has revealed that it will be challenging to find time to film the second series of Sherlock.

Cumberbatch, who plays the titular Sherlock Holmes, admitted to the Wall Street Journal that it will be difficult to shoot more episodes, but praised co-star Martin Freeman (Dr John Watson) for his new role in The Hobbit.

The actor said: "It’s great simply knowing that we’re going to do more episodes. I get peeved when people say that the show’s being pushed back because of Martin’s work on The Hobbit.

"We would both happily return to working on Sherlock and Martin actually initially said no to doing The Hobbit because he thought it would conflict with shooting Sherlock. Now, they’re working around his schedule. I obviously want him to have the experience of being the hairy-footed one."

Cumberbatch also emphasised that he loves working alongside Freeman on the show.

"He’s extraordinary," he added. "During auditions, the minute he stepped into the room I said to the producers, 'I don’t know if you want my opinion, but I want to work with him, because he makes my game better'. I honestly felt myself get better as an actor playing scenes opposite him. He has a brilliant level of humanity."
