Revealing mistake: When Gregory throws Tree through the window during the final fight, as Tree lands, you can see the outline of a stunt-pad on her thigh beneath her pants. You can also tell it's a stunt-woman, as her body is slightly stockier than Tree normally is.
Revealing mistake: When Tree accidentally runs off the hospital roof, you can get a quick but pretty clear look at the stunt-woman's face as she falls, right before she hits the ground. The stunt-woman's body is also very slightly stockier than Tree's actress Jessica Rothe.
Revealing mistake: When Tree kills herself by throwing herself out of a plane, in the shot where she lands in front of Carter and Danielle, it's very blatantly obvious she was filmed on a greenscreen and comped in. The lighting on Tree doesn't quite match the lighting of the scene, and there are very obvious and unnatural hard lines around her hair where the background was rotoscoped/keyed out.
