Puzzle #t1:
I’m thinking of a movie. Can you guess it?
Ask yes or no questions only. One question per post, please. Build on the answers given to others to arrive at your conclusion. If you don’t get it in 30 questions, I win.
Question One: Did it win at least one Academy Award?
Yes.
Was it released since 1990?
No.
Was it released on or after 1965?
Yes.
Did it win Best Picture and a Best Actor or Best Actress Academy Award?
Is it a Western?
No, no, and no.
Is it a children’s movie?
Did any of the following actors appear in it: Paul Newman, Dustin Hoffman, Robert DeNiro, Meryl Streep, Gene Hackman, Jack Nicholson, Jane Fonda, Robert Duvall, or Jack Warden?
Are you counting this as two questions, tdn (your answer suggests you are)?*
*And, no, this shouldn’t count as a question, but is meant for clarity purposes only 
Yes, one of them.
I’ll count your AA question as one question, but it did not win for direction nor acting. It was nominated for both, though.
Is the running time longer than 2 hours?
I’ve found at least one movie that meets all the above criteria.
Was the movie a winner of the Cannes Palme d’Or?
Yes.
Yes.
I feel that you are close to a solve.
Taxi Driver?
Not Taxi Driver. (Great guess, though.)
I missed this question.
Oh.
Hell.
NO.
20 questions left.
Then I think it’s gotta be MASH.
