Created that unknown stuntman/actor:

His name must be in the cast list of THE CRANE/RIVALS OF THE DRAGON - the HKFA has two names in the cast who are not in the hkmdb (and unfortunately are listed in no other movies).

ID of that actor:

Name is Sa Au (probably a alias - real birth name could be in THE CRANE). Name and actor in YOU ARE WONDERFUL (coming soon: cast page of that movie with many first IDs), MANTIS FISTS... and DEADLY SNAIL... .
