Lucy Liu, Elementary
How You Know Her: Liu's breakout TV role was as the cold, ruthless and hypersexual lawyer Ling Woo on the legal dramedy Ally McBeal. She was also one of Charlie's angels in the film franchise.

She once again plays a cold problem-solver, this time as the gender-bending Watson, a former surgeon and sober companion to Jonny Lee Miller's Sherlock Holmes, in the updated adaptation of the classic detective tales.
