It was Fernando Poe Jr. vs. Zaldy Zshornack in an action picture they co-produced, Walang Daigdig (1959). FPJ and ZZ first co-starred in the youth-oriented Lo Waist Gang and from then on they shone either as solo stars or in tandem with each other.
Walang Daigdig is actually the story of three brothers, the third being Rodolfo Cristobal, then being built up by Larry Santiago Productions, which released the movie.
Leading lady is Cielito Legaspi, the future wife of Pablo Santiago, who directed the pictures. — RKC
