A movie that came out a few years ago, She's All That, directed in 1999 by Robert Iscove, is about a girl who has pretty much gone from rags to beauty in a few short weeks, and also learns how to act like a lady. This was a very hard task for Layne Boggs (Rachel Leigh Cook) to do, much as it was for Audrey Hepburn who played Eliza Doolittle in the 1964 movie, My Fair Lady, directed by George Cukor and based on George Bernard Shaw's 1913 Pygmalion.
I watched She's All That a few nights ago and was able to see the similarities between this movie and My Fair Lady. I considered She's All That to be a 90's remake of My Fair Lady, with a little more modern take. In both of these movies, the main female characters were asked to be the "project" of the main male actor. Layne Boggs was remade for the prom, much as Eliza was remade for a very special ball that she would be attending to with Prof. Henry Higgins.
While their male co-stars are remaking these ladies, both set of actors begin to fall in love with one another. Once the love-plot begins to set in, the women realize that they are being "played" by the men and quickly want to give up on the process of becoming a lovely lady that they have been so diligently working on for the last few weeks.
After the women give up, I believe this is the point that the male co-stars realizes what they will lose if their respective women would give up and walk out on their project. They will lose much more then a bet that they have wagered; they will lose potential loves that they are now becoming attracted to. Once they have realized this, they quickly change their behavior; and of course the fairy tale ending of the couples falling in love is how the movie ends.
