The 20-minute Making Of is the only extra, which is fine if you like this kind of thing. Personally, I don’t, unless you learn something about how the film was made, or what the director hoped to achieve, or why the lead actor is a prat.

In this case, the director Julien Leclercq is a cue-balled clever clogs, or, to be more precise, he is serious about what he does and somehow this suits the French. When Americans or English directors intellectualise about filmmaking, they sound pretentious. Not Julien. He sounds committed and compares his job to that of a Formula One racing driver.

It is interesting to see how they work with CGI, as well as listening to the fight choreographer describe the difficulties of arranging a punch up in a bathroom (“I prefer a gym; I prefer space”). Albert Dupontel, who plays David Hoffman, insisted on doing his own stunts, which is impressive considering how violent this movie can be. Melanie Thierry loved playing Manon (“Sometimes I forgot to act because I was so fascinated by her”) and when she tells you, she smiles like an angel. You feel you have died and gone to PR heaven.
