Glenda Jackson, who returned to acting in old age after a long career as a politician, has died.
My favorite movie of hers is the one in which she played Richard Nixon.
Under disguise, of course. It was called Nasty Habits and was Watergate set in a nunnery. Thoroughly chortleable. Geraldine Page played Haldeman and Sandy Dennis was John Dean.
A recently deceased person of great infamy who made a principal character in some surprisingly good movies was Theodore Kaczynski. I recommend Ted K in which he's played by Sharito Copley, and also the miniseries Manhunt: Unabomber in which he's played by Paul Bettany, although that's more about the heroic, put-upon FBI agent played by Sam Worthington.
