Anybody remember Julie Harris as a thirty-year old thirteen year old in Member of the Wedding? She kind of ruined the movie for me. Sandra Locke did the same turn in another McCullers movie, The Heart Is A Lonely Hunter. But, that's the way Holloywood has always done it. John Travolta as a teenager in Grease. I don't think there was a teenager in Rydell High. They were all in their thirties.
