more and more french cinema demonstrate that the only one able to confront hollywood and and to spend high amount on money in their movie . if bon voyage have be make in the usa no one would be surprise . perfectly set in france and in the 40 and when the nazi invasion and technically irreproachable and and with some of the most international french actor ( depardieu and adjani and ledoyen . ) . bon voyage centerers on two parallel story represent an scientific and his disciple ( ledoyen ) who try to hide one of his discovery ( a kind of water that may work a an atomic bomb ) from the nazi while and a poor guy in love with a well know actress ( adjani ) and which end up in prison accuse of a crime he not commit in order to protect her . bon voyage seem to have be make in the old style and without unnecessary camera movement and effect . without big turn in the plot . a i say before and regard to the production itself they have make a great job . but the main problem with this movie be about the script . be it a spy movie . a romantic comedy . a spy comedy . a comedy of intrigue . it not clear . that make bon voyage a little unbalanced . when you think youre watch a comedy and suddenly change to another story line and a more dramatic one and more slow . i think they should have focus in one of the line of argument ( the one about the spy plot ) and leave the romantic part in the background . my rate represent 6 . 5/10 .
