Black's exact motives are unknown. We do know that he was ultimately responsible for Strange's dismissal from the clergy, but we do not know his reasons.

Ian Richardson's credits are too numerous to mention, but he is probably best known for his role as Francis Urqhurt in The House of Cards and To Play the King. He was also memorable in Gormenghast, The Magician's House and Murder Rooms.
