Han’s Gruber’s death scene was terrifying for Alan Rickman
Talking about unintentional reactions, Rickman’s death scene was genuinely scary for the actor. In order to make it look like he was falling off a building, he was supposed to drop 20 feet down onto an airbag. In order to get a genuine fear reaction from him, instead of dropping him on the count of 3, the stunt man let go on 2, scaring the crap out of him.
