This was excellent movie! Great action from Hark and Van Damme. The plot wasn't any special but better than ever before. I have seen every Van Damme movie and this was the best. In his later movies there was only this this serious guy with big muscles and karate/kick and thai-boxing, but in this movie there's little bit comedy which is good. Knock/off reminded more of a Jackie Chan movie then a normal Van Damme movie because of the comedy and the action sequences. Van Damme has never climbed a wall or used a shirt or chain and what ever to kick some butt, but in Knock/off he does and its OK! If you have never seen a Damme movie, rent this.
