It doesn't seem like it would really be all that hard, like that would be a pretty simple movie project. Like 1 step up from a documentary... All you need is some cheap shit to break, some people that know karate, some flexible people, video editing + FF/RW, maybe a green screen and some harnesses Besides that all you need is a cool location, your story line, and some slow motion scenes that LOOK cool, but are really simple, since it's not really happening, and you can just pretend for slow-mo, and do it "really good" Like you could make shit look epic pretty easy https://www.youtube.com/watch?v=glsUlacDN7Q"]Kung fu hustle final fight scene - YouTube https://www.youtube.com/watch?v=102jJCjTbdY&feature=related"]Kung fu hustle musicians vs landlords - YouTube
Hell yeah, the voice acting or even just the acting in general is always cheesy in kung fu movies anyway. It wouldn't be a very high budget movie to make.
