 To prepare for her role as Elle, Reese Witherspoon (qv) spent two  weeks studying the behavior of sorority girls, as she did not wish  to portray a stereotypical airhead sorority image. She states on the  DVD commentary that they were all very kind and polite, and she  enjoyed her time with them. She also observed women shopping from  the café at Neiman Marcus, and attended law school for a day.
