Girls Just Want To Have Fun(1985)
Janey Glenn (Sarah Jessica Parker) is an Army Brat who loves to dance. When she moves to a new town, she meets a fellow dance enthusiast named Lynne Stone (Helen Hunt) at the parochial school she attends. Although they have many difficulties with authority figures and other teenage issues, they achieve success on the show "Dance TV".
This is another 80s movie that's been damned as cheesy and corny...Even by the people who enjoy it. This is one of those movies that can determine what type of an 80s person you are. I would recommend seeing it and then making your own judgments.
This is the theatrical trailer in a different aspect ratio and without watermarks.
