If ourmath checks out, Witherspoon attended the festival forher first film, "The Man in the Moon,"which with hindsight clearly launched a stratospheric film career.

Back in 1991, hints of future megastardom lay in thefilm's New York Times review:

"Mr. Mulligan also gets an outstandingly natural performance out of Miss Witherspoon, who has no trouble carrying a lot of the film single-handedly," Janet Maslin wrote. "It falls to her to remind the audience that this story is at heart about a family, and she does."
