"Sherlock" star Benedict Cumberbatch has strict theatre etiquettes. The actor, who was part of the "Hamlet" performace in London last week, has requested fans not to illegally record the live show.

The official opening of "Hamlet" is on 25 August, but the production had its first preview last week and it's now battling leaks. According to Vanity Fair, media critics and fans should be blamed for the leaks.

The play has been reviewed by critics from three leading journals and has reportedly received mixed response. While the Daily Mail and The Telegraph were quite impressed, The Times not as much.

Now, the website pointed out that the reviews are unacceptable and has categorised it under leaks because as they should technically not be published until the play's official opening.

Apart from this, Cumberbatch  has pleaded fans, who gathered outside the Barbican centre after the performance, not to illegally film the live performance.

"I can see red lights in the auditorium, and it may not be any of you here that did that, but it's blindingly obvious. It's mortifying, and there's nothing less supportive or enjoyable as an actor being on stage experiencing that. I can't give you what I want to give you which is a live performance that you'll remember — hopefully in your minds and brains whether it's good, bad, or indifferent — rather than on your phones," he said.

The actor, who recently welcomed a son, went ahead and asked fans to put technology to good use and spread the word about "Hamlet" through social media. "I don't use social media. I'd really appreciate it if you did tweet, blog, hashtag the shit out of this one for me," he said.

Now, it looks like Benedict Cumberbatch fans will have to wait to watch "Hamlet" on 25 August.
