Sam, Juliet Stevenson and Ian Mckellen will perform in "Shakespeare and the Law" (16 November, Middle Temple Hall). The event has been organised by Peace Brigades International (PBI) and the Alliance for Lawyers at Risk.
Juliet and Sam have previously worked with PBI. In May 2013, they performed in a gala honouring defenders of the rule of law.
Sam went to the Photograph 51 press night on Monday. Rather appropriately, he wore a tie with a periodic table on it (wooller.com and his Twitter, @exitthelemming). Andrew Scott and Harriet Walter also attended the event.
Earlier this month, Sam discussed artist Frank Auerbach in Art Quarterly (via @artfund).
Parents in Performing Arts will have a campaign launch at the Young Vic on 16 October. Romola Garai and Poppy Burton-Morgan are confirmed to speak. Sam and John Simm are listed as supporters on the Eventbrite listing.
Sam endorsed the arts policy proposed by Christian Wolmar (via @wolmarforlondon). Wolmar was a candidate seeking nominations to be Labour's candidate for Mayor of London.
