Crew or equipment visible

When Laura is walking down the street before she trips, you can see reflections of a crew member in a high-vis vest helping the camera follow her down the street.

Audio/visual unsynchronised

When Laura first gets in the van at the flats, she doesn't shift gears at any point. Her left hand is seen on the wheel even though the engine can be heard changing. As she turn in front of the stadium, you can see it's a manual transmission transit van.

Continuity

Laura parks the van beside the fogged road and is then shown walking away from inside the cab. Though she is walking away in extremely dense fog, the driver's wing mirror (which remains in shot) shows that there is no fog to the rear the van.

Continuity

When The Female descends down the escalator at around the 10 minute mark the camera angle switches from behind her descending the escalator with her to a fixed camera in front of her as she approaches. At that switch, the persons in front of her on the escalator are different in than in the prior shot.

Revealing mistakes

(At around 01:38) The black latex under the fake human skin is ripped and folds, revealing Scarlett Johansson's actual skin at the tail bone.

Miscellaneous

As the female is driving around looking for men the camera perspective is intended to be from the view of the Female. But several times prior to the 13 min mark the shot is clearly from the left side of the vehicle (the passenger side vs the drivers side).
