Though the Northern Ballads and its variations had been adapted to local folk theater, I think the reigning God of Malayalam film production Sri. Kunchacko who owned the biggest studio of those times, Udaya saw the mother lode of a possibility by translating them on screen. Sri.Kunchacko, I think, was the Yash Chopra of the Malayalam film industry.He started off the filmi ballads with Unniarcha, a B& W production, in 1961.
Sri.Kunchacko added variations, brought in new characters, spun off sub-stories, all of them wrapped up in the same gaudy, kitschy costume trains and ornaments borrowed straight from the local theater. I always thought there was a divine connection between the bright and flaring silk embellishments to its ‘original’ counterparts across the sea, the Samurais of Japan! 🙂
