Anachronisms: In one of the first sequence you can see slightly blurred in the background the logo of the LCL bank (yellow letters on a blue background). The LCL name/logo was only introduced around 2005 and there did not exist yet in 1984.
Anachronisms: In a hospital scene towards the end of the film, the pillow behind the actor's head reads "HOPITAUX DE PARIS 2006" on the design in numerous places, though the film was supposed to be shot in the 80s.
