I used Ian Holm, who plays Lear in the 1998 BBC production (the one with the red walls)
), and Johnathan Miller who directed the 1988 production (the one that attempted to recreate an elizabethan production)

readings
productions
context
reception over time (which was in the rubric, but not in the question - which was a bit annoying, but at least i found it!)
