Factual error: When Elias shows Kyle the syringe full of succinylcholine, the liquid is brown. Succinylcholine is colorless. He also describes it as something that will basically get them high, which is not what the substance does (although that part may be deliberate deception - even if he does not hide at all the fact that an OD would kill them, so the purpose of such deception is unclear).

Factual error: Avery crashes the car on purpose at top speed against a street lamp and undoes at the last moment Petal's safety belt. Neither airbag is deployed on impact. (01:16:10)
Factual error: In the climax of the movie, Nicholas Cage uses a nail gun like a marksman, hitting with precision the bad guy that holds his wife tight. Besides this skill of his coming out of left field, a nail gun does needs a surface against the opening. It does not shoot nails in the air without pressure being applied, it's a Hollywood trope.
