The ensemble cast—largely made up of young, first-time actors—delivers natural, affecting performances. Ikal, the narrator, provides a reflective and earnest point of view; Mahar, Lintang, and the rest of the Rainbow Troops are distinct personalities whose friendships form the emotional core. The adult characters, especially their devoted teachers, Bu Muslimah and Pak Harfan (or in some adaptations, Pak Harun), embody compassion and moral conviction, elevating the film’s ethical stakes. The chemistry among the children feels authentic, which enhances the film’s poignancy and relatability.
