Who has acted in the comedy film XXX?
Terang Boelan
The film, which included the songs ``Terang Boelan'' and ``Boenga Mawar'' (``Rose''), required its cast to sing keroncong music (traditional music with Portuguese influences); because Mochtar's voice was ill-suited to the task, the musician Ismail Marzuki -- who also composed the film's score -- sang while Mochtar lip synced.
