GOOD GIRLS GONE BAD
How about some movies featuring actresses who are almost always good girls but who suddenly turn up bad? Thought you’d never ask!
Mary Tyler Moore practically defined the chirpy good girl in her two long-running TV series, and was also the good girl in films like Change Of Habit (1969) and Thoroughly Modern Millie (1967). Then came Ordinary People (1980) and Ms. Moore is the dysfunctional member of a saddened family who has lost a child. Donald Sutherland and Timothy Bottoms are doing their best to cope, while she mopes and just can’t shake her depression. She was nominated for an Oscar, but lost out to Sissy Spacek for Coal Miner’s Daughter. 
Donna Reed is one of the last actresses you’d pick to play a hooker, heart of gold notwithstanding,. The All-American girl in movies like It’s A Wonderful Life (1946) and her own long-running TV show, she is nonetheless a prostitute in From Here To Eternity (1953). And this movie has another surprise entrant: Good girl Deborah Kerr, starring in films like The Sundowners(1960) and The King And I (1956), appears as a very adulterous wife, rolling in the surf with Burt Lancaster. 
Girl-next-door June Allyson, good as gold in Little Women (1949) and The Glenn Miller Story (1954) turns up as the hateful wife from Hell in The Shrike (1955), driving poor Jose Ferrer into a mental hospital (and into the arms of good girl Joy Page).
Anne Bancroft is very sweet in 84 Charing Cross Road (1987) and is almost saintly as Helen Keller’s teacher Annie Sullivan in The Miracle Worker (1962). But her most famous part, by far, is as the wicked Mrs. Robinson, seducing overmatched Dustin Hoffman in The Graduate (1967). Her angry face as Mr. Hoffman rescues Katherine Ross from the altar is not quickly forgotten.
Who doesn’t love Jodie Foster? We’ve watched her grow up in the movies. She is a sweetheart in movies like Candleshoe (1977) and Silence Of the Lambs (1991). But in  Elysium (2013) she is the extremely vicious Secretary of Defense of the stellar location of the rich and powerful, dispatching bad guys to kill off the miserable poor saps trying to become citizens of the idyllic utopia. Okay, I know she played a 12-year-old whore in Taxi Driver (1976) but she was mostly a helpless victim. 
And while we know Meryl Streep can play absolutely anything, she still stuns us as the worst boss ever in The Devil Wears Prada (2006), driving poor Ann Hathaway (and much of the audience) to distraction with her arbitrary devilish directions. 
By the way, I can’t seem to come up with any Bad Girls Gone Good movies. Any ideas?
