The unsuspecting tickle
One of the adorable scenes between Johnny and Baby was when he tickled her arm and she burst out laughing, but this wasn’t in the script at all. What ended up happening was that a long shoot that went way into the night got Jennifer Grey acting up. Screenwriter Eleanor Bergstein explained “It was very late at night and we were all exhausted.
Jennifer [Grey] is ticklish and she started to laugh, and Patrick got exasperated.” She added,”When we saw it, we burst out laughing, and when Jennifer and Patrick saw it for the first time, they burst out laughing because we’d completely forgotten that this had even happened.”
