Of the actors…
Are you asking who was the best actor or who deserved these awards most?
Ideally—Glenn Close for Best Actress in Fatal Attraction (1987) and Dangerous Liaisons (1988).
If it’s best overall actor, I would say Tracy. If it’s these two performances (which is how I interpreted it) then I would say Hanks.
Not sure I would give any of them both of their wins, but:
5. Hanks (how the hell is he winning this poll??)
Ideally: Al Pacino for Godfather Part 2 and Dog Day Afternoon.
Hmm. Don’t feel too enthusiastic about these specific wins, but Tom Hanks gets my vote.
