Last night on The Tonight Show, Jessica Chastain recounted the time Al Pacino offered her some of his long-cultivated wisdom. To set the scene: Chastain, starving actress that she'd been, was simultaneously chatting with her "acting godfather" and hoarding free food from the craft service spread when Pacino perked up with "Jessica, I got a piece of advice for you."
