The film was shot in black-and-white. As the Dutch East Indies government was preparing for an expected war with Japan following the German invasion of the Netherlands, the crew was not allowed to shoot scenes at sea. Instead, scenes showing the pirates were shot at the shore of an inlet in Batavia (modern day Jakarta). Other scenes used unused footage from The's previous work "Alang-Alang" ("Grass"; 1939). Some scenes were inspired by Hollywood films; a scene where Ferry Kock's character bites a rencong during a fight, for example, was inspired by a scene in Tarzan films; "Alang-Alang" and the later film "Poetri Rimba" ("Jungle Princess"; 1941) also drew inspiration from the series.
