So, the house lights go down, Ralph Fiennes, as Oedipus, enters, comes downstage and says, ‘Citizens of Thebes, I...’ and the mobile of the woman sitting two seats down from me goes off. She reaches into her bag and shuts it up, then tries to turn it off completely, thereby making it ring again!
To his credit, Mr Fiennes did not walk off in disgust. I might have.
The companion of the woman in question arrived fifteen minutes after the start of the play and plonked herself in the empty seat next to me: she obviously was the person who had been calling at such an inopportune moment. I saw them both later at the Press Night party: they were with one of the actors in the Chorus. People who are somehow involved in the theatre can be the worst audience.
