Gangland Odyssey (1988) Cantonese?

This entry says language is Cantonese.
This is a Taiwan movie (not to confuse with the 1990 Gangland Odyssey), filmed in Taiwan with mostly Taiwan actors, except main actor Alex Man.
Even though Alex Man's voice can be heard only in the Cantonese version (not sure about his real voice, at least it's that distinctive voice he usually has in his HK movies), I feel strange calling the original language "Cantonese" just because of Alex Man. The other actors sounds more authentic in the Taiwan version to me (except Alex Man), apart from Mandarin they sometimes speak Hokkien, too.
