The 1978 movie is full of heartbreak and milkshakes and lots of 50s nostalgia. This movie covers quintessential high school moments: the big pep rally, the school dance, worrying about image, and, of course, falling in love. "Grease" was the word when this movie came out in 1978, and the word is still alive and well today, as evidenced by the movie's ever-growing legion of fans.
