Continuity mistake: When we see Aimée painting for the first time she is sitting at the kitchen table. When the camera cuts to a close-up of the picture it's quite different from the one in the wide shot. (00:23:20)
Deliberate mistake: After Emily talks to inspector Girotti she starts a record player. Then she walks over to the window, sees Werner in the garden, and decides to go down. Between shots she appears behind him, which is wrong, as the song from the record goes on, but it's most probably intended. (00:30:45)
Other mistake: When Tom is lying on the road closely inspecting the local ant population, the doctor's cinquecento has to brake and almost skids off the dirt road. However, there was no need for such an emergency stop since the doctor was driving quite slowly and Tom was still about 50 meters away from where the car stopped. (00:45:35)
