Arianna Huffington

Arianna Huffington sits on Uber's board as one of the few adults in the room, a media mogul lending the company a veneer of respectability it badly needs. She watches Travis Kalanick's chaos with a cool, appraising eye, choosing her moments, playing a longer game than the boys around the table realize.

The performance finds dry comedy in restraint itself, in the way she lets silence do the work of a rebuke, making her the most quietly dangerous person in any scene she's in.
