"Entourage," the much-anticipated big-screen version of the award-winning hit HBO series, reunites the show's original cast, led by Kevin Connolly, Adrian Grenier, Kevin Dillon, Jerry Ferrara and Jeremy Piven. Movie star Vincent Chase (Grenier), together with his boys, Eric (Connolly), Turtle (Ferrara) and Johnny (Dillon), are back...and back in business with super agent-turned-studio head Ari Gold (Piven). Some of their ambitions have changed, but the bond between them remains strong as they navigate the capricious and often cutthroat world of Hollywood.
