Greatest Guerrilla Ever

A film all about Disney World, shot inside Disney World, without Disney's permission. 

This is "Escape From Tomorrow"

People shoot videos at Disney World all the time, often times documenting their vacations and the fun things they did in the park. There is no way Disney could ban recording devices from the park without a major backlash. But that being said, there are certain things that they don't want filmed, such as behind the scenes places or closed buildings. This doesn't stop people from trying to get footage, but Disney keeps a watchful eye to make sure they don't get very far.

A notable example of this is "Adam the Woo" (One of his videos is posted above), who has snooped around Disney with his camera so much, that they banned him from Disney World entirely.

So what would happen if somebody decided to shoot an entire movie there, without Disney finding out?
Well, one of this year's Sundance films did just that.

"Escape From Tomorrow" follows a father on vacation with his family at Disney World, and delves into the mental breakdown he has while in the park. The filmmakers got themselves under Disney's radar while shooting, using iPhones and handheld cameras as to not rouse suspicion. Whether or not Disney will try and keep this movie from bring distributed to wider audiences is unknown. Untill we find out, we have the trailer:
