Funnyman Chris Rock chose to direct himself in new comedy I THINK I LOVE MY WIFE after realising his first choice wasn't married. The comedian admits he and the unnamed filmmaker had a series of "creative differences" on set - because the director he helped hire couldn't understand what it was like to be in a committed relationship. In the film, Rock plays a married man resisting temptation as he struggles with the monotony of his relationship. He says, "We had a falling out. He wasn't married and it's really a married person's movie... Only married people understand marriage."
