"How did I do?"
"Glenda Jackson couldn't have done it better."
Glenda May Jackson, CBE (born 9 May 1936) is a British Labour Party politician and former actress. She first became a Member of Parliament (MP) in 1992, and represented Hampstead and Kilburn until 2015.
As a professional actress from the late 1950s, she spent four years as a member of the Royal Shakespeare Company from 1964, being particularly associated with the work of director Peter Brook. During her film career, she won two Academy Awards for Best Actress: for "Women in Love" (1970) and "A Touch of Class" (1973). Other award-winning performances include Alex in the film "Sunday Bloody Sunday" (1971) and the BBC television serial 'Elizabeth R' (also 1971); for the latter she received an Emmy.
So this means that there definitely is a televersion for Glenda Jackson. Her only TV appearance as herself (apart from talk shows, variety programs, and news specials) that technically qualifies as being a part of Earth Prime-Time would be when she appeared on 'The Muppet Show' in its fifth season. She proclaimed herself to be the dread pirate Black Jackson and proceeded to take over the theater as though it was a galleon.
(When she contradicted Kermit the Frog at the end to claim that she really was a pirate, it could be that she was momentarily possessed by the spirit of her ancestory.)
At any rate, she is acknowledged as a great acting legend in both Toobworld and the Trueniverse.
