• Continuity

    (at around 33 mins) Julian is sitting in the front passenger seat of the Jeep and is not wearing a seat belt. When the driver speeds into the tree, two people fly out of the front windshield--neither of which are Julian. Not only is this preposterous, given that Julian didn't have a seat belt on, but this also means that someone behind him flew through him to fly out of the windshield.

  • Continuity

    (at around 24 mins) When the cell phone video shows a man getting mauled at the zoo, the phone and a woman's fingers are perfectly still. Later, the same women has the same phone from a different angle, and she is constantly shaking.

  • Factual errors

    (at around 25 mins) Lions don't rip off the arms of a person standing up; they kill by suffocation first.

  • Factual errors

    A lion can't rip a person's arm off without biting through connective tissues.

  • Incorrectly regarded as goofs

    The plants are releasing a neurotoxin that turns the brain's self-preservation mechanism into a self-destruct mechanism. When Mrs. Jones is affected, she rams her head into the windows to let the gas into the house. That could be a more efficient way to self-destruct. Similarly, the driver of the car Julian was in tried to kill himself instead of others inside the car.

  • Incorrectly regarded as goofs

    (at around 22 mins) When the train stops in Filbert, the conductor tells Elliott that they've "lost contact." When Elliott asks who they lost contact with, the conductor replies, "Everyone." People get off the train and use cell phones, and the stranded passengers watch TV news in the diner (which has power). The train engineer is probably referring to the train controllers, not everyone in the world. He is likely also exaggerating due to his emotional state.

  • Plot holes

    The neurotoxin causes people to kill themselves, not others yet no one thinks to protect themselves by handcuffing or otherwise securing their bodies so they can't harm themselves.

  • Revealing mistakes

    (at around 24 mins) The man in the lion cage was obviously shot on green screen. The lighting between the man and the rest of the scene doesn't match.
