Notable role: Mary Katherine Gallagher in Superstar (1999)

Molly Shannon and physical comedy go together like peanut butter and jelly, or radio hosts and Schweddy Balls. Case in point: her two most popular characters (drawn from a pool of many, the result of a six-year run on SNL) the high-school-superstar Mary Katherine Gallagher and 50-year-old Sally O'Malley.

Kristen Wiig sums up what makes Shannon great perfectly: "The amazing Molly Shannon, she's just completely fearless." There was no fear each and every time she plunged her fingertips into those damp, stubbled armpits.
