This person called Siddhus has dug up some wonderful archaeological filmi treasures for YouTube. Let’s hope these stay up. However, the labeling is confused (and confusing). The song is “Bharata Samudayam Vazhgave,” as it says on the YouTube post, but the film is not Nam Iruvar. The name of the movie is Vazhgai, the film that got remade two years later into the Hnidi film Bahar.
If Vyjayanthimala had been in Nam Iruvar, she would have been only 11 years old. That’s wrong. She is a bit more mature in this film. She is probably the same age as Kamala was in that other movie: 13.
