Here are 15 things about the movie that you probably didn't know, even if you're a huge fan!
SHAREif you know the words to songs from Grease,even after all these years.
1. "Hopelessly Devoted To You" was added to the film after filming ended because the producers wanted Sandy to have a solo ballad. That went on to be the only song nominated for an Oscar.
2. Carrie Fisher was considered for the role of Sandy.
The director (whose roommate was Star Warscreator George Lucas), saw her film a battle scene in Star Wars, Episode IV: A New Hopebut wasn't convinced she would be the right fit.
3. Even the background dancers had names, which included Bart, Bubba, Moose, and Sauce.
4. Jaime Donnelly was growing gray hair that had to be dyed black for filming!
5.
Greasehad a product placement agreement with Coca-Cola. It fell through too late in the production process and any products that would have appeared in the films were blurred out.
6. Marty, played by Dinah Manoff, can't dance and sat out of every dance scene.
7.The creators of Greasealmost made the movie animated
instead of live action. When that idea was scrapped, they decided to make the opening credits animated as a nod to the original idea.
8. "You're The One That I Want" took just one afternoon to film!
9. Annette Charles, who played Cha Cha, checked herself out of the hospital to film the drag race scene, and then had emergency surgery that night from an ectopic pregnancy.
10. Cast members got sick after filming this scene because the water was stagnant and full of bacteria.
11. The lyrics "Elvis Elvis let me be, keep that pelvis far from me" in the song "Look at Me I'm Sandra Dee" was added in because Elvis Presley died the day they filmed that scene.
12. Even though the actors were portraying highschool students, they were actually much older in age.
Oliva Newton-John was 28, Stockard Channing was 33, Kelly Ward was 20, Jamie Donnelly was 30, Barry Pearl was 27, Didi Conn was 25, Michael Tucci was 31, Dinah Manoff was 19, Jeff Conaway was 26, and John Travolta was 23.
13. Rizzo's "Hickeys from Kenickie" were actually real!
Jeff Conaway, (who played Kenickie), insisted they be authentic, and gave them to her himself. 
14. Jeff Conaway had a really big crush on Olivia Newton-John, and was nervous around her on set. He ended up marrying her sister.
15. Olivia Newton-John wasn't sure she'd make a convincing high-schooler, so she requested a screen test before she accepted the role. After shooting the "drive-in" scene, she was happy with how it looked and took the role.
16. The movie is based on a Broadway musical with the same name. The musical was so popular that it had 3,388 performances and has been revived twice since!
17. Danny's blue windbreaker is a direct nod to James Dean. James wore a red windbreaker in
Rebel Without a Cause.
