Visible crew/equipment: When the ambassador and the photographer are in the cemetery getting attacked by the dogs there are men standing behind a tree. I'm assuming they're the trainers - they are located when the photographer is trying to hop the fence. Look in the back right hand corner - there are about two or three men standing there.
Audio problem: When Thorn and Jennings are at the apartment in Italy they are talking about Bugenhagen and Jennings says that he is an exorcist and has read about him. However, his lips continue to move even after he has finished speaking. Although the camera is on Thorn and Jennings is blurred in the background, his facial movements are still easy to see.
