Editor's note: Teenage angst is teenage angst, whether you were a teen seventy years ago or now. But the music and the dance culture of the 1950s makes for a particularly good musical, and John Travolta absolutely lights up the screen in this film version. Talented Brit Olivia Newton John (R.I.P.) tugs at our hearts as the innocent Sandy, and the supporting cast is top-notch. Relive the fun of a great movie with some cool Grease wallpapers!
