Dame Helen Mirren is a great signer. Depending on the usual equation – the demand divided by the time allocation – she either signs her quickies, which are “H Mirren”, or, if you’re lucky, you get the full “Helen Mirren”.

Over the years she has signed a number of my sketches. On this occasion it was the European Premiere of Graham Greene’s classic crime thriller Brighton Rock at the Odeon West End in February 2011.
