To Be Or Not To Be … Rude?

If you’re planning on catching Benedict Cumberbatch as one of Shakespeare’s most famous characters, bring your enthusiasm for the Bard but please – above all else – leave your recording devices at home.

The Sherlock star, who just began headlining in Hamlet at London’s Barbican theater last week, is already sick and tired of seeing his fans recording his performance as literature’s most indecisive Dane. Cumberbatch claims there is “nothing less supportive or enjoyable” than being on stage and seeing a “big red light” in the audience.

Cumberbatch’s Hamlet is one of the most in-demand shows of recent years and tickets sold out fast due to the actor’s popularity. However, that acclaim comes with the price of some fans attending no doubt with the sole mission of seeing the actor who plays their favorite consulting detective. Because of the unwanted attention, Cumberbatch told people gathered outside the stage door on Saturday that spying the filming while he was performing was “mortifying.” He asked fans to spread his message through social media, warning that future offenders could be evicted from the show.

William Shakespeare’s Hamlet, directed by Lyndsey Turner, runs through October 31 at the Barbican in London. Tickets are sold out.
