One of Poe Senior’s big hits was Palaris, a cloak-and-dagger historical romance. Poe senior had made his fame on such films, an extension into the cinema of the moro-moro tradition. In late 1954, Mario Barri, who had worked for the elder Poe, thought of doing Anak ni Palaris and he cast Ronnie in it, making the boy assume his father’s name to emphasize the picture’s relation with the old Palaris. For his first movie role, Ronnie got a thousand bucks and co-starring billing with Rosita Noble and Mario Escudero---but this picture proved disappointing. “One thing I know, it didn’t make money,” Ronnie recalled.
