Visible crew/equipment: In the scene where she drives the car (with the kidnapped woman in it) down the hill towards the breaker/electrical box, when she hops out at the very last second you can clearly see a person dressed all in black sitting in the driver's seat driving the car down the hill.
Visible crew/equipment: When Robbie takes Sil home, a reflection of a boom mic can be seen on the glass door behind him.
Visible crew/equipment: When the alien is driving off with the guy from the club in his BMW, you can see the entire crew reflected in the passenger side door as it drives by.
Suggested correction: They never said Sil was a natural predator when they created her. She was half human and half alien and it was their belief that human females are more docile (i.e. more motherly, more gentle, more empathetic, and less aggressive than human males). Although the reply to "more docile and controllable" was "you guys don't get out much", meaning that girls aren't that docile and controllable.
