And Olivia
Age Gap In Grease
Is Unexpected
When "Grease" came out in June 1978, it became a bonafide success, and the film remains a cult favorite. If you're not a super-fan, you may not know a surprising fact about the age difference between the movie's stars, John Travolta and Olivia Newton-John.
Newton-John was five years older than Travolta, who was just 23 when he filmed the movie, while she was 28. There may have been an age difference between the two, but they quickly formed a close relationship, and they remain friends to this day.
Newton-John said she was worried about taking on the role due to several factors, including her age; however, after some discussions and agreeing to meet Travolta, she signed on. Newton-John said of the screen test she insisted upon, "When we walked inside the room together, it was magic, and everyone saw it."
