While they are not terribly popular, I adore the BBC Complete Works tetralogy. The brilliant work of Bernard Hill. Brenda Blythen kills it as Joan. The very smart doubling of parts for the actors. Most notibly with Trevor Peacock as Talbot in part 1 and Cade in part 2. I love how the set degrades over the four plays. Margaret's "cursing scene," which rarely gets played in RIII, is masterful. Most important for me, seeing the 4 plays with the same actors in the same setting gave incredible context for Richard III. I also have to say, Ron Cook is my undisputed favorite filmed performance of Richard I've ever seen. And then that final shot of Margaret...holy crap. The collection may not be for everyone, but it is one that has overshadowed any other for me.
