It's hard to imagine a world where Rachel McAdams didn't serve those telling glances as Regina George, but the role almost went to other members of the cast, including Amanda Seyfried and Lindsay Lohan. In an Entertainment Weekly, Lohan recalled, "I wanted to play Regina. I had just played — in Confessions and Freaky — not the cool girl in school. I was still 17 years old and I wanted to be the cool girl on set. So I had a war with him [director Mark Waters], and he goes, 'No, Cady is the heroine, and that's who you are.'"
