Movie - The Assassin

I watched the original French version of this movie a long time ago on SBS. It was one of those movies with concepts so cold, with characters so well "executed", that the scenes just stick into your brain never to leave! When the "Hollywood" version showed on Win here the other night, the temptation to watch it was too strong to resist. Although this version was nowhere near as well "executed", the memories of the original came back and I was shaking and having cold sweats half way through. The final assignment on this version however, and the "Cleaner" sent in to clean the assassinations by killing all witnesses, just didn't ring true. I kind of want to see the original again, but I fear the nightmares might come back.
