Having worked in investment banks as a trader for many years, I always watch movies related to the industry. Some cannot capture the atmosphere of a trading room but this one actually does. Even if some bits are a bit simplistic -for that kind of size Kerviel traded a lot on the phone and with a lot more discretion-. Also a key component of JK being able to cheat the Soc Gen was to access the middle office system thanks to his previous position; this is totally absent from the movie. The fun part is the characters: his boss played by Demaison is exactly the kind of fat f**k psychos you find on a trading desk, FX plays it perfectly. Also his further bosses (the meerkat midget and the curly hair) are very close to their real life counterparts... Believe me I've know them (sorry guys). Basically those clowns had no clue what was going on and never questioned a trader who was making his budget 10 times over. They only lost 5 billion, making them the worst desk managers of all time. JK was totally out of his depth, dishonest andincompetent never makes a good combination but Soc Gen should haveknown better. Served them well.
Worth watching, way better than JK's book at least.
