90. Mean Girls (2004)
Director: Mark Waters
Stars: Lindsay Lohan, Rachel McAdams, Lizzy Caplan, Lacey Chabert, Amanda Seyfried, Tina Fey, Tim Meadows, Amy Poehler, Ana Gasteyer
If you ever wonder "How the hell did Lindsay Lohan get so famous?" then you clearly haven't seen the superb high school comedy that made her a star. Tina Fey blessed "Big Red" with a surprisingly smart screenplay that foreshadowed her 30 Rock style (but none of LiLo's fuckery).
