Kappu Bilupu

Kappu Bilupu () is a 1969 Indian Kannada language film directed by Puttanna Kanagal. Based on a novel of the same name by Aryamba Pattabhi, this movie revolves around the contrasting behaviors of an identical, yet distinct pair of twins. The film starred Kalpana in dual roles. Puttanna himself remade the movie in Tamil as "Irulum Oliyum" and in Telugu as "Iddaru Ammayilu".
Puttanna used the movie as a medium for speaking to the youth of the ideals he derived from Vivekananda. The settings are simple and mostly rural. The story is about how domestic peace was better than a glamorously consumptive lifestyle. The juxtaposition of the two sisters played by Kalpana in a black and white background was a clever trick. K. S. Ashwath and Balakrishna play dignified elders who in many ways are sympathetic but helpless. There were a couple of simple but moving melodies.

Story.
A Cinderella-inspired story. A commentary on the ultimate triumph of good character over situational advantages. Kalpana in her first role is a well-mannared girl who is being ill-treated by her stepmother. Her second character indulges in a wanton lifestyle bereft of kindness.

R. Rathna composed the music for the soundtrack.
