Which Pulitzer Prize winning plays also won the Oscar for Best Picture?

There has been only one person to win a Nobel & an Oscar, it is none other than the Irish playwright 'George Bernard Shaw who' had won both the Nobel Prize for Literary contributions & for his work on his play Pygmalion in 1925 & went on to win an Oscar for his adapted screenplay for the movie "Pygmalion" based on his own work in 1938.

He never wanted his plays to be turned into Musicals during his lifetime, but later Alan Jay Lerner made it into one of the most astounding musical's in 1964 named "My Fair Lady" winning multiple Oscars, he took great care to retain much of the original play& the way of speech while making the movie.
