just water usually means you don't have the terrain loaded that the film was shot on. If you had just flown it you must have had the terrain. Only thing I can think of.... and this is just a guess, do you have two installs? If the game you play is saved in something other than the default, and the film version of the game is in say the default location, it wouldn't update the terrains in the film location, only the game location.
