In 1995, Gross and Levenson published the results of their test screenings. They came up with a list of 16 short film clips able to elicit a single emotion, such as anger, fear or surprise. Their recommendation for inducing disgust was a short film showing an amputation. Their top-rated film clip for amusement was the fake orgasm scene from When Harry Met Sally. And then there’s the two-minute, 51-second clip of Schroder weeping over his father’s dead body in The Champ, which Levenson and Gross found produced more sadness in laboratory subjects than the death of Bambi’s mom.
“I still feel sad when I see that boy crying his heart out,” Gross says.
