American political pundit James Carville's acting skills have been slammed by THE ASSASSINATION OF JESSE JAMES director Andrew Dominik, after shooting a cameo role for the movie. Dominik claims Carville was unprepared and has sworn never to work with him again. The 40-year-old film-maker tells PageSix.com, "I didn't want to hire him in the first place. He came unprepared. He couldn't get his lines out right. It's like he has ADD. It took us three hours to shoot that one small scene." Carville, the man who has been credited with putting Bill Clinton in the White House, concedes, "Did I nail it the first time? No, it took a little while. Casey Affleck helped out a lot. No one is going to confuse me with Laurence Olivier."
