Ari Gold (Jeremy Piven) in Entourage

Ari Gold

Ari Gold is the self-proclaimed “most powerful agent in Hollywood” and is responsible for getting Vince paid throughout much of the series’ run. Though it’s probably Ari’s over-the-top drive that has earned him his high standing, his bullheadedness also proves to be an impediment in both his professional and personal life, especially during later seasons. Ari and Vince’s manager Eric Murphy share a tepid rivalry in Entourage, yet the superagent also serves as a mentor for the up-and-coming manager when he’s truly in need.
