About an hour and 15 minutes into the movie, the doctor is explaining how the nerve gas pill works. He has no glasses on. He turns and walks over to a device, still with no glasses. He stops, the camera cuts to another angle, and he has glasses on.
Throughout the film Lisa (Anne Dupont) doesn't wear any jewelery. When she is kidnapped, she is unconscious and carried away by the villain and is clearly wearing a metal watch on her left wrist. However, she was not wearing the watch up to the point where she is snatched by the villain and it's gone by the time she regains consciousness.
