Downton Abbey stars Michelle Dockery and Iain Glen are among the cast of BBC Two's upcoming Shakespeare season and will appear in Henry IV.
Dockery, who plays Lady Mary in Downton Abbey, will play Lady Percy, while Glen, who plays Sir Richard Carlisle in the ITV series, will play Warwick.
The BBC productions of Henry IV Parts I and II star Jeremy Irons as Henry IV, Tom Hiddleston as Prince Hal, Simon Russell Beale as Falstaff and Julie Walters as Mistress Quickly.
The cast also includes Joe Armstrong (Hotspur), Maxine Peake (Doll Tearsheet), Niamh Cusack (Lady Northumberland) and Alun Armstrong (Northumberland).
Filming will begin in January 2012 and the BBC will also film adaptations of Richard II (played by Ben Whishaw) and Henry V (played by Hiddleston) for the season, which is part of the broadcaster's contribution to the London 2012 Festival and the Cultural Olympiad.
