OK, this one's another great challenge.

I'm reading up some of the reviews of the title "Demon Fighter", which many sites are treating as an alias for the Xenon release "Faster Blade, Poisonous Dart". As best as I can gather, both titles features Adam Cheng, Briggite and Roc Thien, and IMDB/Amazon treat them as the same movie.

The claim in several reviews is that Roc Thien is in the movie, but it's a bit part, and not a major starring role (even though his name is featured prominently on the box covers).

To further add to the confusion, "Faster Blade, Poinsous Dart" doesn't point to "Demon Fighter" as an alias at HKMDB, but "Lone Ninja Warrior", which stars neighter Lin nor Cheng, but does star Roc Thien.

Question
a) Is "Faster Blade, Poisonous Dart" an alias for "Demon Fighter" (instead of Lone Ninja Warrior
b) Is Roc Thien in a bit part in "Demon Fighter"?

Demon Fighter (1982)

Lone Ninja Warrior:

I don't see Roc Tien in Demon Fighter, and he's not in the cast list for that film.

According to ProjectAKA under a search for "Faster Blade Poisonous Darts"

"The US Xenon VHS edition of Faster Blade Poisonous Darts is the film Demon Fighter where the UK Eastern Heroes VHS is Lone Ninja Warrior."
