Don't start worrying about stunt casting: Dean O'Gorman may be a star of certain Middle Earth-based blockbusters atm, but he's far from as well-known as the actor he's been hired to portray in an upcoming biopic of screenwriter Dalton Trumbo. Yep, a biopic of a screenwriter, and a very deserving one at that too, I'd say. O'Gorman bears enough of a resemblance to actor Kirk Douglas to make his casting as the iconic Hollywood actor very appropriate. They have the same eyes, I think. Bryan Cranston will play Trumbo in the film, which is to be directed by Jay Roach, and the cast also includes John Goodman, Helen Mirren, Michael Stuhlbarg and Diane Lane.
