I read that Patrick Swayzee was frustrated with Jennifer during Dirty Dancing because he was trying to teach her to dance.
That is on the DVD about making of Dirty Dancing, VERY interesting DVD, I recommend it for anyone who is a fan of the movie.
In his new autobiography, The Time of My Life, Swayze wrote: “We did have a few moments of friction when we were tired or after a long day of shooting.
“(Grey) seemed particularly emotional, sometimes bursting into tears if someone criticise her. Other times, she slipped into silly moods, forcing us to do scenes over and over again when she’d start laughing.
