Why not make it a guest interactive, "Choose Your State" adventure?
Have little keypads for each seat with abbreviations of all 50 U.S. states.
Have 50 different versions of the film, one flying over each U.S. state.
Riders can punch any key and the film automatically changes to the version of whichever state they choose.
The musical score remains the same regardless.
If another rider in another seat hits a button for a different state, the film changes to their selection, so on and so forth.
It all becomes a battle of who has the best reflexes in their fingers.
Also wouldn't be a good idea for people sensitive to strobe effects to ride, considering how quickly the screen will be changing films throughout, as riders battle it out pushing buttons, switching states, etc.
