Olivia Newton-John spoke out against fans who have recently slammed her iconic film "Grease" calling it sexist and misogynist.

"I think it’s kind of silly," the 72-year-old said on the podcast A Life Of Greatness. "I mean, this movie was made in the 1970s about the 1950s."

Newton-John played high schooler Sandy Olsson who falls for local bad boy Danny Zuko (John Travolta).

"Grease" aired over Christmas 2020 on the BBC and prompted people to express their opinions on Twitter, according to the UK Express.

One person said, "The drive-in/botched make-out session between Danny and Sandy hasn’t aged well. Film kinda glides right into song ("Sandy") before viewers register the date rapey vibe of the scene they just saw #Grease."

Another said, "Ahhh man. Just watching #Grease one of my favorite films and it’s so of its time. Misogynistic, sexist and a bit rapey."

Someone else pointed out there was very little diversity onscreen. "There were no Black actors or pupils at the high school," they wrote. 

Newton-John pointed out, "It was a stage play, it’s a musical, it’s fun. It’s a fun movie musical not to be taken so seriously."
