Several night scenes, especially the one near the end, were clearly recorded during daytime under bright sun. This fact was clearly noticeable by the shadows of people and trees, and intensity of light compared to the shadows. In order to make the time in such scenes appear to be night, the picture was drastically dimmed out.
In the beginning of the movie, Dr. Aqil and later his brother, with no prior experience of or information about vampires, know exactly how to kill one.
During the climax, the fist fight seemed to have taken place during night-time but when a widow opens, there is bright daylight outside.
