Another day, another reason for the Sherlock fandom to go crazy.
We had to inform the BBC that Martin and Benedict had commissioned a new series. They signed themselves up. They both announced that they were carrying on - so that's good. Benedict, at some red carpet event somewhere, said he was carrying on forever. Martin, at another one, said, 'Yep, series four is happening'.
This all goes back to something Benedict said at the South Bank Show Awards in March.
All I know at the moment is we're doing these three and another three. I just don't know what there is beyond that. It just depends on Martin and I's availability, how long we can keep it going. It depends on Steven's ability. I'd love to keep it going.
