Richardson — fresh off her Golden Globe-nominated work on Nip/Tuck — will appear in five episodes of the show's final season, which focuses on the dark final days of King Henry (Jonathan Rhys Meyers). She follows Tazmin Merchant as Henry's fifth wife, Catherine Howard.
The Tudors is currently filming in Ireland, and its fourth and final season will begin airing on Showtime in 2010.
The role was reportedly one of the most sought-after of the TV season, and at one point, the producers reportedly wanted Gillian Anderson to take it. Do you think Richardson is a good pick? Are you eager to see her act regal?
