Mr. Daniel Day is my pick for top of all time. Sorry Bogart, but this guy is amazing! The Last of the Mohicans, There will be Blood, Gangs of New York, Lincoln, etc. Seems like I love every movie that he is in. Gangs and Blood are neck and neck though. Cannot choose which one he does the best in.
I do not know if Ms. Streep has the most Oscars of all time yet, but she sure has plenty of nominations. Year after year she shows us why she is the best in the business. She even does action and comedy well. Death becomes Her and The River Wild are proof of that. Not the best movies, but they get the job done usually.
Who is your top actor and actress of all time?
