4. Diane Farrow (Sandra Bullock) in 'Love Potion #9' (1992)

Sandra Bullock has the overly bushy eyebrows, frizzy hair and unfixed teeth that any pre-makeover lab rat would have, but "Diane Farrow" sounds more like the polished woman about town she becomes after she starts testing a love potion in the name of science. Soon, she's got every man at her feet, including the Prince of England.
