At the test screening, the movie ended with Reese Witherspoon's Elle kissing Luke Wilson's Emmett, then cutting to a year in the future when Elle and a now blonde Vivian (Selma Blair) hand out Blonde Legal Defense Fund pamphlets on campus. Co-writer Karen McCullah told Entertainment Weekly, “The test-screening audience didn’t feel like it was an exciting enough ending for her, success-wise." So while still at the movie theater, the filmmaking team brainstormed the graduation speech ending.
Reshoots soon commenced, and if you look closely at the last two scenes, you'll notice Witherspoon's hair is more reddish. This is because she was in the middle of shooting another film, The Importance of Being Earnest, when she did the reshoots. Also, Luke Wilson wore a wig, because he'd shaved his head for The Royal Tenenbaums.
