6. Grease (1978)
One of the most famous romantic movies ever without a doubt. This is a romantic film with plenty of music, plenty of dance and lots of feelings.
Plot: Danny (John Travolta) and Sandy's (Olivia Newton-John) love story begins with the classic premise of good girl meets bad boy, but from there it parts ways with any kind of archetype. Newly transplanted from Oz, goody two shoes Sandy comes to Rydell High, only to discover that her sweet summer love is actually the bad boy leader of the T-Birds. Jibes from the other Birds and the Pink Ladies keep the two apart until Sandy decides to take a walk on the wild side -- perfectly in key!
Main Cast: Olivia Newton-John, John Travolta, Jeff Conway, and Stockard Channing.
Mood: Upbeat and groovy.
Rotten Tomatoes Rating: 6.7/10.
