HBO has picked up the new dramedy from Entourage's Doug Ellin.

Variety says the action revolves around a fortysomething hedge fund trader and his circle of guy pal; Ellin describes the series like, "What if the guys on Entourage grew up?" He also says it's a "mature version of Entourage set on Wall Street."

Ellin is working on the script that he cites several real-life situations as the basis for the pilot; production is set to begin later this year or early next year.
