Speaking of “Mean Girls”, we almost never got to see Rachel McAdams in the first place; Lohan was actually selected to play the Queen Bee herself: Regina George. Lohan gave the role a second thought, and the casting director agreed that she would be a better fit as the lead role of Cady. Lohan didn’t request a bigger role, she just didn’t want to play a nasty character because it would damage her reputation. Good thinking Lindsay, we certainly wouldn’t want to damage that reputation any.
The cast had a major shuffling over the course of film preparation, as Seyfried and Lacey Chabert were also considered for the role; McAdams ended up landing the part because ironically she was actually polite, and seemed a bit too nice. Tina Fey felt that McAdams’s demeanor would be more believable for someone as manipulative as Regina George, and the result ended up working perfectly.
