Jones and Vanessa Redgrave did Much Ado as B&B when they were 82 and 75 years old. I read that it was bad, but the world must be peopled (and no, they apparently did not cut that line).
The Sher version of Lear is from the RSC, it's available on a few different streaming services. I haven't seen all the filmed RSC stuff but they've done the best versions I've seen of a number of the plays: Richard II, the Henry IV's, Lear, Love's Labour's Lost, Much Ado (which they released under the gimmicky title Love's Labour's Won). They have a few duds though: their Merchant of Venice is very ill conceived and their Tempest is so drowned in FX and elaborate makeup that it doesn't really come to life.
