The War with Grandpa

Released three years after filming took place.

Ed uses a drone to listen in on his grandson's conversation by hovering it outside his bedroom window. Not only do drones not have microphones, as there are generally not many sounds that can be recorded hundreds of feet in the air, but even if Ed had installed his own microphone, it would have been useless over the sound of the drone and through a pane of glass.

After the first set of credits, some bloopers are shown, alternated with the cast dancing together.
