I wish an American distributor had picked up this over-the-top Hong Kong comedy, because it may have helped to break down the unfortunate fact that Americans for the most part are still pretty closed to foreign films. Granted, it's far from a conventional comedy, and not easy for advertising to sum up, but I think this could have been at the very least a sleeper hit on these shores had a distributor patiently opened this across the country.
But you should be able to find this in any good Asian movie rental place in your city. You don't have to worry about any cultural differences - much of the humor is of the international slapstick variety, and even some of the cultural references (like Shaolin kung fu) will be understandable. Now there are some kinds of humor that even had me (who's seen much more of Asian cinema than the average humor) mystified, but there was still a wacky edge to them that made them amusing, even if I didn't know exactly what they were referring to.
The movie is a non-stop barrage of laughs. It does get exhausting at times, and the movie starts to get really sloppy towards the end (the final scene felt very unfinished), but you'll still find much more to enjoy here than in your average American comedy. Even if you end up hating it, you won't be able to deny that you've seen NOTHING like this before!
