Thornton, 58, will play a billionaire cowboy-turned-film financier who puts up money for Vinnie's new project, a big-budget Dracula film. In the Entourage movie, Thornton's character sends his 20-something son to Los Angeles to keep an eye on his investment.

Production on the highly anticipated flick started two weeks ago.

Thornton will next star in FX's limited series Fargo.
