Sam will star as Garry Essendine in Present Laughter at the Theatre Royal Bath next year. It will run in the theatre's main house from June 22 to July 9; press night will be on June 29 (The Stage).
The play will be directed by Stephen Unwin, who collaborated with Sam on Henry IV Parts I and II (English Touring Theatre, 1996-1997). This is the second time Sam has played Garry Essendine - in 2013, he played the character in a BBC Radio 4 adaptation of Noel Coward's play.
Tom Hollander, Hugh Bonneville, Penelope Wilton and Sam will read at the Cancer Research UK Christmas Concert, 15 December at St Paul's Cathedral (via his Twitter, @exitthelemming).
He received the BAFA (British Arts Festivals Association) award for Outstanding Contribution to the Arts 2015 (National Campaign for the Arts Twitter, @artscampaign).
