In this undated handout photo provided by the Almeida Theatre on Friday, April 11, 2014, actress Katie Brayben is seen wearing a mask that depicts Britain's Prince Charles during a scene from the play 'King Charles III' at the Almeida Theatre in London. A new play about Britain's future king is getting rave reviews. Once it would have been theatrical treason. "King Charles III" imagines current heir Prince Charles taking the throne, with catastrophic results. Just a few decades ago, depictions of living British monarchs were banned from the country's stages. (AP Photo/Almeida Theatre, Johan Persson) NO ARCHIVE
