Benedict Cumberbatch is urging theatregoers not to film his performances on stage.
The actor is currently playing the role of Hamlet at the Barbican Theatre in London.
He says it was "mortifying" seeing someone with a camera on Saturday night when he was trying to deliver the famous "To Be Or Not To Be" speech.
Cumberbatch went on to say that there's "nothing less supportive or enjoyable" than seeing a "big red light" in the auditorium. It prevents the actor from putting on a great performance. But he doesn't mind them taking pictures outside afterwards.
During this impromptu statement, filmed by Kari 100, the actor is urging people not to film the show and to spread the message on social media.
"It will get strict from now on. They've got devices that will have people detected and evicted. I don't want that to happen. That's a horrible way to police what's a wonderful thing. So this isn't me blaming, it's just me asking you to ripple it out there on your funny electronic things."
