Hopefully these images are useable!! I picked up the UK Rarescope DVD as soon as I realised there were Chinese credits on the disc as an extra.
The 2 duplicate caps are from the dub print which is in better shape! One mystery is already solved - why was a 'Peter Poon' always listed as producing the film? See the Production Manager credit

Is it possible that the HKMDB entry should be changed from Chinese Hercules now?
