Why is it that so many dubbed HK videos from this group (Wu Tang Chess Boxing collection, Wu Tang Collection, etc. . .) have video covers that do not match the videos inside them?

I just picked up "Chess Boxing, The Next Level" with a picture of Mark Long ("The Ghost Faced Killer") on it. The back of the box says all sorts of stuff about how he appears with "a shaved head" and all this nonsense.

Too bad the movie didn't have any of that. Not once did a picture of the "Ghost Faced Killer" appear in the movie. Clearly this was a scam.

What other movies should I now know to avoid?
