Grease is one of the beloved movies of the 1970s starring Olivia Newton-John and John Travolta, and also one of Travolta’s family members.
The film’s success set up huge careers for many of the cast members who are now mostly in their seventies, particularly John Travolta who was just 23 when the movie was made.

The movie was the highest-grossing musical film of all time upon its release and still exists in the top 30 musical films even in 2025.
