Does anyone know why John Woo's main name was changed into John Woo Yu-Sum? What romanization is this? And in what movie was he credited like that? And why does "John Woo" not even appear as an Alias even though it's his most common name?
Driven by this questions, I have now checked as much movie credits as possible, here are the results:
Only Chinese credits:
The Time You Need a Friend
Happy Union 2
Don't Cry, Nanking
Wu Yu-Shen:
The Boxer from Shantung
The Water Margin
Young People
Four Riders
Wu Tsung-Shen (today added as a new Alias):
The Blood Brothers
Wu Yu-Sheng (today added as a new Alias):
The Young Dragons
The Dragon Tamers
Princess Chang Ping
The Hand of Death
John Y. C. Woo (today added as a new Alias):
The Pilferer's Progress
John Y. S. Woo:
Follow the Star
Last Hurrah for Chivalry
John Woo:
Hello, Late Homecomers
Plain Jane to the Rescue
From Riches to Rags
A Better Tomorrow

Bullet in the Head

Ghost Bustin'
Love, Lone Flower
