(at around 9 mins) The shots of Zack and Hanna riding in a seaplane to visit their father on Lake Wipissing were taken inside a stationary plane with computer effect scenes seen through the side windows, but most of the computer effect shots were taken with a camera pointing in the direction of flight while the windows on which they are displayed are side windows looking perpendicular to the direction of flight, resulting in the plane appearing to be flying sideways in various shots.
