Filmmaker Benjamin Lancaster spent four years secretly shooting a science fiction movie called “The Further Adventures of Walt’s Frozen Head,” working with actors Daniel Cooksley and Ron Schneider to make a movie about a WDW cast-member who discovers the (urban)-legendary frozen head of Walt Disney, kicking off a series of adventures around the park. The movie premieres online later today. This is (at least) the second time someone has secretly shot a movie at Walt Disney World. (Thanks, Hugh!)
