Please note: The director's stated this is a fantasy, and not meant to be an historically accurate film, so any mistakes along those lines won't be permitted.

Revealing: In the final scene of the movie, when Evolet and D'Leh are embracing by the river, the water in the river is completely static, without so much as a ripple, for the entire scene, even though the reeds are blowing in the wind. Submitted by wizard_of_gore
