You answered your own question. It was the fact that John Travolta was a huge star, plus 1950s nostalgia (which was all the rage at the time). Also, it was an adaptation of a very popular broadway musical.
That's true, but nobody thinks these days 'oh that's the adaptation of the musical', I believe it's superseded it completely, unlike say 'Phantom of The Opera' the movie, when you say 'what do you think of Phantom' most aren't going to think of the movie. But if you say 'what do you think of Grease?' I'm sure everyone will automatically think of the movie.
AFAIK "Grease" the musical is still a staple of many High School drama productions so its familiarity even with kids under the age of 20 is more palpable than something like "Happy Dayz" or "American Graffiti" which are cut from the same cloth in terms of pop culture era. When I was in high school in the 80s many of the 70s pop culture icons were already phased out and not part of the youth culture I was growing up with BUT the movie "Grease" still had its foothold with people my age and it stood as an ubiquitous reflection of American pop culture then even though it was reflective of the 50s nostalgia of the 70s.
Plus, ONJ was a megastar in country and pop at the time. They even added Hopelessly Devoted to You just for her. Some folks forget that song was not part of the original Theater show.
That's true. I have another idea. The cast is basically all adults (ranging from 19 to 32) being high school kids again. Some definitely look their age. I think we wish we could let go of our responsibilities and have fun as a 17 year old again. I know Olivia Newton John said that she actually felt like she was having a do-over of her teenage years and enjoying something she didn't have. Olivia went to an all girls school so it was a completely different experience.
I too wish I had a cooler highschool year than I had.
Yeah, some of the songs are nice.
But I don't really like it otherwise, because of the dumb "you have to change your hair and your wardrobe and start smoking" message.
I also thought she was just showing everyone that she could be the bad girl if she wanted and do it better than any of them. She was the same ole Sandy the next day.
The message of the story is pretty much that being "squeaky clean" is boring and reactionary.
Because totally changing yourself to please other people makes you a rebel, somehow...
Yea, John Travolta was coasting on his fame from Welcome Back , Kotter into Saturday Night Fever and Grease until a infamous movie,Moment by Moment released in 1979 stopped his momentum cold and nearly wiped his fame out until Urban Cowboy in 1985 started his career going--his fame is mostly miss or hit.
A few years ago, I bought the double blu ray of Saturday Night Fever and Grease. I bought it mostly to watch Saturday Night Fever. The famed movie critic Gene Siskel called it his favorite movie of all time. So I wanted to check it out. Other than some nice dance scenes and some catchy music, I didn't really l like it all that much but I guess for Siskel it hit all the right notes. But then I watched Grease and that was a great surprise. I made the mistake of watching Grease 2, too. That was a huge mistake. One of the worst sequels I've seen.
