“We honestly don’t know [if this season will be the last]. These three [episodes], we’ve very, very pleased with them. And everybody’s very keen to carry on. It’s just genuinely difficult to schedule everyone’s diaries. It was a nightmare to schedule this season… and that’s not going to go away. I mean, the success of Doctor Strange is not going to make Benedict short of work.”
[Sherlock is] an extraordinary gift, we certainly don’t want to wave goodbye to something like that lightly.”
However, allowing for the possibility of cancellation, he adds:
“There is a great precedent for leaving well alone. [The classic UK sitcom] Fawlty Towers is twelve episodes, with four years apart. And it’s perfect.”
As for whether Sherlock could end only to be revived decades down the line, he said:
“Right at the beginning, we said, wouldn’t it be fun — because we start with the first meeting, which is very rarely dramatized — if we actually ended up with them at the same age as Basil Rathbone and Nigel Bruce? That would be a really interesting place to be with Benedict and Martin, having started so early in their careers as young men.”
The fourth and potentially final season of Sherlock premieres Jan. 1 on BBC One and PBS.
Stay tuned as we continue to monitor the cancel/renew status of Sherlock Season 5…
