Other mistake: When Rex shakes the table causing the baby monitor to fall, the batteries fall out and we see the open battery compartment with markings for positive (+) and negative (-), and space for two AA batteries. Woody jumps off the bed and places the two batteries inside the compartment, but before he closes the compartment note the position of the battery closest to the top of the monitor. The positive side is actually where the negative side should be so the monitor should not work, but the monitor turns on just in time to hear the soldier's warning. (00:13:15)
Other mistake: In the scene where Robin Williams tells Sarah that she needs a 12 to win, she rolls a 3. The next time she rolls, Robin tells her she needs a 7 to win.
Other mistake: When Johnny Cage is fighting Scorpion in the forest, after Scorpion unleashes his snake-like spear from his hand but before the camera switches to Johnny, you can see the spear move down and it appears to be coming out of his forearm. Also the hole in Scorpion's hand from the spear is now gone.
Other mistake: It's pretty bright in the cemetery considering that there are barely any lights.
Other mistake: As the priest walks out of the haunted mansion with his head twisted, you can see the head and body don't step in time together.
Other mistake: In the scene where they are 1st landing at Bangor it is known that there is no electricity at the airport. If you look closely during the landing you will see that the runway lights are on. (00:50:40)
Other mistake: When in the Swan boat, Marie has her arm hanging out with her fingers dragging the water, making waves. She is lying down and back in the boat, with a wing obstructing her view. Yet somehow the reflections of the waves show her face, perpendicular to the boat. Not parallel like her face actually is to the boat, and also somehow reflecting her face despite both a swan wing being in the way, and her being down in the boat out of view of those waves.
