I got chills and they're multiplying and I am losing control. I loved the movie Grease I don't know how many times I watched it. I find myself singing along with the songs. It's a good classic movie.

Incredible how much chaos, risk, and last-minute decisions were hiding behind such a joyful film. This really shows that Grease didn’t become iconic because everything went smoothly—but because it survived everything going wrong.

Had no idea about half of these facts. The story about Olivia Newton Johns leather pants being sewn onto her is wild, cant believe they pulled that off during filming. Also crazy how most of the cast were way older than actual high schoolers but still made it iconic. Grease is truly timeless, thanks for compiling all these behind the scenes details.

I saw Grease from the swings at the drive in theater in Texas City as a kid with my parents.. In 78' I guess I was 8 years old. Good times

I saw this movie when I was in elementary school with my elementary school friends. Ed had the record after we saw the movie. Then we danced and acted out the movie our way. We had a great time.

Amazing that Rizzo's pregnancy subplot was considered "inappropriate s3xual content for teenagers" to the point it would be rated R. Wonder what they thought of "16 and Pregnant" on MTV (which didn't moralize or condemn the teens it documented and made stars). So many current music videos would be rated R or X by the standards back then.

I was 8 years old when GREASE was released. I have watched it 89 times throughout the years. 😘 Every character and song. I wish I still had my GREASE ALBUM.
