Stockard Channing, who played Rizzo, the leader of the Pink Lady's in Grease, was 33-year-old at the time of filming, making her 15-years-old in real-life than in the film.

Okay this one is our favorite. Barbra Streisand, in the 1983 film, 'Yentl' plays an ambiguously young, "girl living in an Ashkenazi shtetl" where her father secretly teachers her the Talmud. Streisand was, get this, 41-year-old at the time of filming, making her the oldest real actor on this list. I mean, wow, for 41, phew.

John Franklin, who played, Issac, the young preacher in the 1984 cult-classic, 'Children of the Corn', was 23-years-old at the time of filming, and actually suffers from a growth hormone deficiency, which makes him appear much younger than he actually is. In the film Issac is nine-years-old, making John Franklin the second oldest character on. this list.
