Oscar Trivia - Actor Edition

I know I haven't been posting like I should have been, but I'm trying to prepare the Oscar update articles. So, just to pass the time, here's some more Oscar trivia, but with some emphasis on the actors. The first people in the comments to get the answers right, will post your name and answer under the question.


1. Which actor was nominated in every decade from the 1950’s on to the 2000’s, only missing the 1970’s, when he was the most successful?

2. Which actor has the distinction of being nominated for Oscars for playing two different U.S. Presidents?

3. Six actors have won Oscars for Best Actor and Best Supporting Actor. Which two won their Best Actor Oscar first?

4. Three actors have been nominated for Best Actor in the same role in two separate films (Peter O’Toole, Spencer Tracy and Paul Newman). Who is the only actor to be nominated for Best Actor and Best Supporting Actor for the same role in two separate films?

5. Who is the only person to ever be nominated for Best Actor and Best Supporting Actor for the same role in the same film?

6. Who is the only actor to be nominated for playing a real-life Oscar winner?

7. Who is the only actor to be nominated for an Oscar to not speak a word of dialogue in a film (post-silent era)?

8. Who was the first posthumous Best Supporting Actor nominee (the only one besides Heath Ledger)?

9. Who is the only person to ever win two Oscars for the same performance in the same film in the same year?

10. Only three Best Supporting Actors have won Oscars for playing a real person who was living at the time of the Oscars. Jim Broadbent and Chris Cooper did it back-to-back in 2001 and 2002. Who is the only other actor to do the same?
