Hollywood was primed when Karl Rove, the senior Bush strategist, came calling. ... Mr. Rove made the case that Uncle Sam needs Hollywood to lend its creative talents to the national struggle by encouraging community service, boosting public morale, and entertaining the troops and by reinforcing the official stance that America is at war with terrorism and evil, not with Islam. Four dozen of Tinseltown's hardest-to-see people came to the meeting: studio chiefs from Viacom, Disney, Paramount, Warner Bros., Twentieth Century Fox, Universal Studios, DreamWorks, ABC, NBC, CBS, Fox, UPN, and WB, plus the heads of the guilds representing writers, directors, and actors.
