Though he plays a news anchor in new movie ‘Morning Glory’, Harrison is not interested in appearing on similar shows and having to speak about his personal life, admitting his public appearances are only related to “selling a product” rather than “truth”.

"I'm not interested in the truth, I'm interested in selling a product. You want the truth go somewhere else. Not my business."
