Olivia Newton-John was 29 years old when she played the role of Sandy Olsson in Grease, meant for a high school graduate. Despite being older than the character, her youthful features and vitality made her very suitable for the role.

The entire film revolves around the change of an innocent girl into a confident woman and the actress could easily slip between those two personas, demonstrating her skills. The age difference was hardly noticeable, as Newton-John's charm and performance helped cement Grease as a classic favorite.
