What's the world's saddest movie scene? Elliot saying goodbye to E.T.? Ray asking his dad to play catch in "Field of Dreams"? The end of "Big Fish"? Terry Malloy telling his brother he "coulda been a contender"? The Superman sacrifice at the end of "The Iron Giant"?
It's basically impossible to watch those with a dry eye, but that's not the film psychologists use when they need a tearjerker. In thousands of studies, researchers rely on the final scene of the 1979 film "The Champ" as a tried-and-true way to turn on the waterworks.
