Sean Gilman’s review published on Letterboxd :
Predictably enough, Johnnie To's section of this three-director film was my favorite, but it's a fun experiment and shows the distinctness of To, Ringo Lam and Tsui Hark. If you're the least bit familiar with their work, it's shockingly easy to tell who directed which parts of the movie, an experiment in proving the Auteur Theory if ever there was.
I watched the version on Amazon Instant and it is dubbed. Be warned and stay away. The only reason I can think of for the persistence of dubbing Hong Kong movies is racism on the part of American film distributors. If Olivier Assayas, Arnaud Desplechin and Luc Besson collaborated on a noir thriller, there's no way it would have been released in a dubbed version in the US. It would have been treated as the high art event of the year.
