All eyes may be on Martin Freeman when he brings Shakespeare's Machiavellian Richard III to life on stage - but for traditional theatregoers, the very worst villains are in the audience.
Fans of the Hobbit star have been accused of breaching theatre etiquette by cheering the actor's very first scene, during which he delivers the soliloquy starting, "Now is the winter of our discontent ... ".
Conventionally, audiences break into applause only at the beginning of the interval and at the final curtain.
However, enthusiastic Hobbit fans, many of whom are first-time theatre-goers, have been accused of ruining some of Shakespeare's most spellbinding moments with their "annoying" and "disruptive" bursts of applause.
One audience member, theatre blogger Claire Dikecoglu, said: "After the opening monologue some fans tried to kick off clapping and cheering, which I found to be disruptive and unnecessary. There are strong views on this, but I was irritated when the audience interrupted the flow of the play to clap and cheer Martin's first scene."
