10. Kristen Wiig
There was Betty Boop. And Rosalind Russell. And Lucille Ball. And now, Kristen Wiig. She's an old-fashioned screwball comedienne, a master of woman-on-the-verge-of-a-nervous-breakdown madcap. But she's also a definitively 21st century talent, a sketch comedy genius whose indelible Saturday Night Live impressions (Judy Garland, Nancy Pelosi, Taylor swift) and creations (the Target Lady, the folk singer Kat) mark her as one of show's greatest performers. And as Bridesmaids proved, she can command the big screen like a proper movie star, and write a pitch-perfect script.
