There is a scene with Danny loading film into his camera. Although we never see what speed the film is, when he takes the picture of Max (at night, under a streetlamp), the picture has fine-grain detail, in spite of Danny shooting with no flash, no tripod, and low light conditions. To get that clear a photo, he would have needed to use a low-speed film, which would require a tripod in low-light conditions. A high-speed film would have produced a photo with far more noticeable grain.
The film is made by an Australian company, and seems based in Australia, but the vehicles used are a mix of right-hand drive (used in Australia, Great Britain, etc.) and left-hand drive (used in U.S., Canada, etc.). When Alan drives Daniel home, it's right-hand drive; when one of the abducted girls gets into the black car, it's right-hand drive; when Sherrie gets up in the morning and goes to the doctor, it's left-hand drive... and yet, she is shown driving on the left-hand side of the road, as they do in Australia.
