When "An Inconvenient Truth" won the Oscar for Best Documentary, and then a few years later Al Gore won the Nobel Prize for Peace, many claimed he had won both prizes. But in fact, the Oscar goes to the director, and that was not Mr. Gore. However, there is one person who has won both a Nobel Prize and an Oscar. Can you name him?
Hint: The Nobel Prize was for Literature, and the Oscar was for Best Adapted Screenplay.
