Toward the end of the movie when Brum Hilda (sp?) jumps out of the window to land on the horse and the horse moves. When she gets up you see that the concrete is broken. Put it in slo-mo when she is falling and you notice that the concrete is already broken before she hits the ground
That happens in a lot of movies. I great example is from Home Alone 2... when Kevin throws the brick at Daniel Stern. The red marks from the brick are on his face before the brick hits him. but I don't really think it's that big a deal.
This is a common trick used in low-budget movies. I must admit that the editing must be really tight in order for this trick to work. Sadly this movie is an exception and the result was far less than pleasing.
This is one of my favorite movies and watching it over a thousand times i have noticed that. it is true if you are trying to see it it is easiest to watch her head. Also the movie is supposed to make stupid mistakes like that. e.g where he sticks his sword out of the window and grabs the set designer's doughnut.
