Other mistake: In the scene where Jenny waits in the car outside an apartment building while David helps a family move into their flat, an older woman looks out of the window of her flat. We see her reflection in the window of the car Jenny waits in. However, the car is standing beyond the corner of the building - there are no windows that could possibly reflect in the car's window.
Other mistake: When the Amazons interrogate Steve they don't know the meaning of the word "crap" yet they know one of the definitions of the word "rack."
Suggested correction: Just because they understand some slang, doesn't mean they should understand all slang.
Well if they're an ancient race then how do they know of the use of the word rack regarding female anatomy? One of them went out into the modern world and learned this? Hera tell them this? Maybe they got internet or a modern dictionary?
Well obviously they know stuff about the modern world. Diana could speak Dutch fluently, not Old Dutch either, but modern Dutch. So they do get information or else she wouldn't have known that. This would include slang.
Other mistake: The DVD cover that has older Dren posing naked with her tail blade or stinger exposed shows her hands on the far right side crossing, and her hand has five fingers. In the movie her hands only have four fingers.
Other mistake: Throughout most of the sequence in Hugh Hefner's office, the framing of the camera cuts the main character's head off. This is not a cinema error, this is bad framing. The framing fixes itself then goes back to cutting the character's head off.
Other mistake: After Precious has her baby, Abdul, her school friends visit her in the hospital as her nurse, "John," is eating lunch with her. When John introduces himself to Precious' friends, he says he is a nurse's aide, and then later refers to himself as "Nurse John." When he stands up to leave the hospital room, you can see the word "NURSE" on his hospital ID badge pinned to his scrubs.
Other mistake: Since the Doctor got her leg injury, every time you see her walk, she does so with great difficulty, yet after they blow up the terraforming plant, she's running away with no problems at all.
