Blooper

When Elsa finds Clive and Dren in the barn, she stands in the wide-open door. In the next shot, from outside, Elsa throws the barn door open and runs out.

When Ginger and Fred meet in the case at the shareholders' meeting, they began to hiss and protract their claws and fangs. From behind, Ginger's fang is already out, and Fred begins to push his out. In the next shot, Ginger pushes her fang out for the first time.

In the first scene when Clive and Elsa take Dren to the barn, it is night, but when they go inside, there is sun streaming through the skylights.

When determining why Dren developed her predatory instincts they state that they didn't use any predators to create her except human. They used both bird and stingray DNA - both are predators.

Dren should have frozen to death given the conditions of her captivity. She has no body hair, very little body fat, and yet she can somehow run barefoot in snow, and swim in a pond with no consequences from the extreme cold. While there is an indoor heater in the barn for her, it's too small for a space as big as that. While the film heavily implies that Dren simply has a very high metabolism as a result of her accelerated growth rate, meaning she would produce enough internal heat to offset the heat lost to the environment, there's still the issue that for an animal her size to maintain its body temperature in a cold environment like that purely through metabolic action, Dren would need to consume enormous amounts of food, far more than what she is shown eating in the film, something close to or exceeding her body mass every 24 hours.

The machine used to create Dren has Blastocyte Implantation on it. That is Carnegie Stage 3, the embryo would be Stage 1.

The scenes at the farm are set in the winter, but the barn where Dren is living has sunlight showing between the boards making up the outer walls. It would be drafty and as cold as the outside, but is shown as warm enough to be livable.

When Dren hangs upside down from the rafter in the barn, her dress doesn't fall down around her shoulders.

In two separate scenes, an outdoor shot of the apartment building shows a gray snowy day, while the interior shot shows sun shining through the windows.

When Elsa returns to the lab after being "sick," the analog clock is set to 3:47, the hour hand points just a bit past the 3, but the minute hand is definitely at the 47 minute mark so the hour hand should be much closer to the 4th tick between the hours.
