Ten, 8.30pm, M ( 2004)
Cady Heron ( Lindsay Lohan) grew up in the African wild, but nothing can prepare her for the dangerous terrain of a US high school. Befriended by three shallow, bitchy girls ( Rachel McAdams, Lacey Chabert and Amanda Seyfried), Cady takes a crash course in sociology. 30 Rock’s Tina Fey, who also appears as the maths teacher, wrote the script, which has lines and observations as sharp as a thumb tack. With a high-scoring joke-to-laugh ratio, Mean Girls doesn’t just make the grade, it takes an express route to the head of the class.
