90. GILLIAN ANDERSON
The House of Mirth (2000)

As Lily Bart, the financially troubled and romantically spurned socialite in Terence Davies' adaptation of Edith Wharton's 1905 novel, Anderson displays none of the unflappability of her X-Files heroine Dana Scully — rather, she undergoes a beautifully modulated meltdown. The striking dichotomy between her big- and small-screen roles makes her journey from serenity to desperation all the more thrillingly alien.
