Notable TV roles: Sloan Sabbith, The Newsroom (HBO); Leigh, Perfect Couples (NBC)

Economist and journalist Sloan Sabbith marks Olivia Munn’s, of G4 and Daily Show fame, first high-profile acting gig—and she’s killing it. A little neurotic and socially awkward, Sabbith deserves credit for being the least frustrating character on a series full of people who tend to do dumb things. Awkward or not, we don’t buy her character’s inability to find a good date in New York City, but everything else is solid. Most figured Munn would go on to do sitcoms; instead she dared to take on Sorkin’s infamously fast-paced, layered dialogue, and met the challenge.
