Terang Boelan [SEP] Introduction
Terang Boelan (; Indonesian for "Full Moon", "Terang Bulan" in the Perfected Spelling System) is a 1937 film from the Dutch East Indies (now Indonesia). Written by Saeroen, directed by Albert Balink, and starring Rd Mochtar, Roekiah and Eddie T. Effendi, "Terang Boelan" follows two lovers who elope after one is almost forced to marry an opium smuggler. The film was shot in the Indies and Singapore, and was partially inspired by the 1936 Hollywood film "The Jungle Princess". It was aimed at native audiences and included "keroncong" music, which was popular at the time, and several actors from Balink's previous work "Pareh" (1936).
