Inspired by a successful French series of the 70s, this film deals with the first mobile brigade, a police force set up in 1907, at the 'Belle Époque', by the Minister of the Interior Georges Clemenceau, nicknamed 'the tiger'. The sets and costumes are excellent, the cast is rather successful except for the main character, the police superintendent Paul Valentin played by Clovis Cornillac in the film instead of the late Jean-Claude Bouillon in the series. Clovis Cornillac is certainly brilliant in Les chatouilles (Andrea Bescond, 2018) or Un long dimanche de fiançailles (Jean-Pierre Jeunet, 2004), but he completely alters the atmosphere of the series, with a charisma without subtlety, always acting like a bull in a china shop. The choice of this actor for this film is, in my humble opinion, detrimental. Otherwise, the film is globally pleasant.
