Revealing mistake: When Nathan and Theresa are talking on the front porch, the background is fake (and mostly blurred). The white picket fence just doesn't look real. A hanging plant on the porch sways a little from wind but the two nearby trees (leaves/branches) are stationary. Next, one tree gets a gust of wind while the other one does not and the remaining trees in the background do not show any movement. (00:13:50)
Continuity mistake: The location and intensity of Lavinia's purple hair highlights vary throughout the movie. For example, the purple highlights on the right side were far more pronounced (two wide, distinct, vivid lines) when she got home compared to when she first met Ward. Lavinia rode her horse Comet home, so her hair would have been wind-blown and the highlights would not have been likely to be neatly straight down, especially since she has long curly hair.
