Yeah, the one in 2001 was way too "chubby", the one in 2013, was also in the ZJZ re-make of Royal Tramp 2008... The main imperial guard, WXB's best friend in the palance, Duo Long.
No matter if it YZ or ZJZ, oftentimes the production studios/investment companies are the same ones or ones w/ slightly different names, but same owners and affiliates. They can be sub-companies or so-called shell companies
They tend to also own the same talent agencies, ad agencies, etc... So it's a business owned by a mere handful of people.... So they tend to use the same bunch of stars, pre-production companies, etc...
It's irritating sometimes that BOTH YZ & ZJZ series, one modern and another wuxia will use the same background music... and same set of supporting casts...
