Are questions concerning martial arts films, their stars, their directors, etc. on topic for this site?
My gut feeling is that some would be a better fit here and others would be a better fit for Movies.SE, which has an existing tag for the martial arts genre.
Here are some hypothetical examples to consider:
- What kind of martial art is Tony Jaa's opponent using in the "burning temple" scene of The Protector (aka Tom-Yum-Goong)?
- How do they do all the crazy flying moves in kung fu movies?
- Is John Woo a martial artist?
- How accurate is the history and style of contemporary wing chun depicted in the Ip Man films made by Wilson Yip, Wong Kar-Wai and Herman Yau?
(In the interest of full disclosure, I'd like to ask that last one myself!)
