Sherlock stars Benedict Cumberbatch and Martin Freeman were the first to know there would be a fourth series of the BBC1 detective drama, says co-creator Steven Moffat at the Cheltenham Literature Festival.– even before himself or the BBC's commissioners.
《神探夏洛克》合伙制片人史蒂芬·莫法特特在切尔滕纳姆文学节上称，该片两位男主角——本尼迪克特·康伯巴奇和马丁·弗里曼是最先知道这部侦探剧会有第四季的人，甚至早在制片人和BBC委员之前他们就知道了。

"We had to inform the BBC that Martin and Benedict had commissioned a new series," said Moffat.
“我们已经告知BBC电视台，马丁和本尼迪克特已经同意出演第四季了。”莫法特说。

"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’."
“他们两个人都签了约。两人都宣布会继续演下去——这非常好。本尼迪特当时正在某地走红地毯，称他会永远继续演下去。另一个男主角马丁也说'是的，会有第四季的'。”

Fans are still awaiting Sherlock series three almost two years after the season-two cliffhanger finale was first screened, with an official air date yet to be announced. And while Moffat admitted he himself did not know for sure when it would be broadcast, he did say "I would place good money on it being at the very end or the very beginning of the year."
《神探夏洛克》第二季摄制之后将近两年了，悬念迭起的剧情未完待续，粉丝还在苦等着第三季。官方网站上的公映日程表也尚未公布。尽管莫法特承认他本人也不知道该剧什么时候能播出，他也说，“在今年年末或明年年初我将会把一大笔钱投入到该剧的摄制工作中去。”
