(CNN) -- Walt Disney World is billed as the "happiest place on Earth," but it's anything but in the subversive new film, "Escape From Tomorrow." Randy Moore's directorial debut focuses on a man who slowly descends into madness while vacationing with his wife and children: Grim reality keeps intruding onto a theme park experience designed to banish every moment of melancholy. In Moore's vision, jolly Disney characters become fearsome ghouls; an epidemic of "cat flu" threatens to sicken visitors; an undercurrent of sex runs through this place meant to stand for innocent family fun. It's a darkly comic and unflattering critique of Disney culture. So why would Disney ever allow Moore to shoot his movie inside Disneyland and Disney World? The answer is it never gave him permission. Moore, his actors and crew infiltrated the parks without Disney ever catching on. The cinematic subterfuge went on for weeks; Moore shot for about 10 days in Orlando, Florida and even longer at Disneyland in Anaheim, California.
