The L.A. Times shares the wonderful story:
To make the movie, Moore wouldn't print out script pages or shot sequences for the 25 days he was filming on Disney turf, instead keeping all the info on iPhones. This way, when actors and crew were looking down between takes, passersby just thought they were glancing at their messages.
Though Moore's actors entered the parks day after day wearing the same clothes, and though Moore was filming with abandon, the production was never shut down by anyone at the parks–in part, the director suspects, because taking out a camera and holding it in front of people at Disneyland is about a natural an act as you can imagine.
Still, Moore worked under some serious constraints, often having to stand with his assistant director across the park and communicating by phone as actors moved in front of his cinematographer, so that it didn't look like a crew was forming.
