In a recent appearance on the A Life of Greatness podcast, Olivia Newton-John (who played the oh-so-innocent character, Sandy Olsson) responded to the backlash; she explained that the film was a "fun movie musical" and not meant "to be taken so seriously" by viewers. "I think in this particular instance, it's kind of silly because the movie was made in the '70s about the '50s," Newton-John said, adding that gender roles were much different back then. "It was a stage play, it's a musical, it's fun," she continued. "I think everyone's taking everything so seriously. I think we need to relax a little bit and just enjoy things for what they are. And I didn't see it like that at all, I think it's just a fun movie that entertains people. That's all."

Whether you loved it or hated it, Grease was pretty popular at the box office, raking in a total of $394.9 million (via Box Office Mojo). And, according to USA Today, the soundtrack "remains one of the best-selling of all time" with "Hopelessly Devoted to You" earning an Oscar nomination for Best Original Song.
