 The exterior shot of the riverboat casino is an actual casino on the  Mississippi River in Vicksburg, Mississippi. The Ameristar lettering  on the "paddlewheel" was edited out and the movie casinos name put  in its place. In the movie, the casino has closing hours while the  Ameristar casino is a 24/7 operation (the entire parking lot beside  the boat was emptied for the shot). Additionally, 2 large river  bridges that would normally be at the left side of the frame are  edited out also.
