These two are the same film.

Writers and 1 director are different...

The crew listing on 'Woman from the Hell' should be the correct one. The other entry has the same people, just Tsai Yang-ming as a writer instead of co-director and the producer being listed as a production manager instead, which seem like reasonable mistakes. This ad makes it clear they're the same film:

If nobody stops me in 15 days I will merge them.
