Not sure about these so post it here for others to decide if these should be merged.

Yeuk Hon Liu Yee Si and Roy Horan

"Yeuk Hon Liu Yee Si" means "John Lewis" or "John Louis". I think "In the Claws of the CIA" was directed by John Liu and his friend Roy "Louis" Horan so they used a merged pseudonym, but I am not sure.

In the credits of the Spanish version only appears Liu as director, but I do not know if this is only in this version or also in the Hong Kong version.
