Was wondering if Punch Pictures Production Company and Punch Pictures can be merged somehow. I'm firmly convinced they're the same company, and since the DB listings contain no pictures, it's possible different editors added the company under slightly different names, perhaps one more complete than the other. The former is responsible for DANGER ZONE, the latter is responsible for it's sequel SOME LIKE IT COOL. Both are sequels to BRUSH UP MY SISTERS, so I'm guessing that falls under their umbrella as well, but I may need to post a screen grab (if I can find the disc) to prove it.
Noticed the company credit on the pro-grade DTV-er MY BABY SHOT ME DOWN tonight and (while wondering why Teresa Mak rarely made it to the big leagues—she's quite good in this) was curious to see if they produced anything else. I'm sure the company is behind more films than the DB suggests, but merging these two entries would be a start at bringing them all together.
Also, Leung Ching-fai and Rocco Leung are the same guy. Screen shots from MY BABY can be provided if required, but their Chinese names in the DB strongly suggest a merge (with alias). Plus, he's billed as Rocco Leung on MY BABY, which should thus become the main name, or at least the alias.
