Judi Dench in The Winter's Tale – Garrick
Michele Dotrice in Nell Gwynn – Apollo
Melody Grove in Farinelli and the King – Duke of York's
Catherine Steadman in Oppenheimer – Vaudeville
A world of hell no for the actor category, I'm embarrassed that Suchet is in here, and only Gatiss stood out for me, so he's my pick. And Dench is undoubtedly a shoo-in but Dotrice is the real scene-stealing delight.
