Factual error: Chucky is not tall enough to rev the engine of the car in the garage when trying to suffocate Nica.
Suggested correction: I watched the scene and it's clear Chucky wasn't using a brick on the accelerator to rev the engine. However, Nica is paralyzed and there are devices you can install on a car that allows a paralyzed person to operate the gas and brake from the steering wheel, so Chucky could rev the engine without touching the gas pedal.
Suggested correction: All he would have to do is stand on the gas pedal.
He's standing at the wheel the entire scene. He's not tall enough to be doing that and pressing the gas pedal.
He could have used a brick or something to keep the gas pedal down and then climbed up to the wheel.
Except if you watch the scene, the engine revs up and down, not something putting a brick on the gas pedal would do.
Factual error: When Ian is checking his laptop and Nica is bound and gagged behind him, you can see her moving her feet a bit, even though she's supposed to be paralyzed.
Factual error: When Nica is pulling herself up the stairs while Barb is in the attic, at one point she calls for Alice. Right after this, you can see her subtly bend her right knee. She's supposed to be paralyzed, so this shouldn't happen. The next time it comes back to her, you can also subtly see her moving her feet and toes a little bit.
