Last time I went more thematic with this category, so this time let me actually take my favorite actor.
Team Actor: Spencer Tracy
I first came across Tracy when I was a kid in 1963's
It's a Mad, Mad, Mad, Mad World - a favorite in our house after the celebrated purchase of our first VHS, a day I still remember quite well. A little later, in my teens, I caught him on cable in
Inherit the Wind and immediately was taken by his commanding screen presence and naturalism. He wasn't classically handsome or typical leading man material but he was possessed of such quiet dignity, grace, and soulfulness that it's impossible not to fall under his spell. Never has another actor ever made standing and quietly listening to his scene partner(s) so compelling.
He was very much tortured in real life, struggled mightily with alcohol, confounded by his faith and unable to openly love the woman of his life because he refused to dishonor his wife by officially ending his long dead marriage, wracked with guilt over his absentee parenting. I think you can see all of that lurking under every performance, even in comedies.
Here he is in
Judgement in Nuremberg, flawlessly delivering a moving 9-page speech in one take:
Tracy's last film was
Guess Who's Coming to Dinner?, for which the insurance premiums for his possible death during filming were so exorbitant that his co-star and director had to put their salaries in escrow to ensure the film got made. Tracy died 17 days after filming was completed of a heart attack.
