Patrick Swayze and Jennifer Grey

They had already grown to dislike each other on the set of “Red Dawn,” so when it came time for “Dirty Dancing,” they weren’t on good terms. Swayze wrote in his memoir, ‘She’d slip into silly moods forcing us to do scenes over and over. We did have a few moments of friction… she seemed particularly emotional, sometimes bursting into tears if someone criticized her.” However, they did eventually become friends.
