Where was Chandralekha filmed?
1948 Tamil film directed by S. S. Vasan
Chandralekha (1948) was filmed in Raj Bhavan, 1 place named in its Wikipedia article's Filming section, in India. Wikidata itself records the shoot only as South India. Each place says where its claim comes from.
Left off on purpose. Not a shoot: The Wikipedia article for this production names Sri Lanka in the part this atlas reads for filming locations, and this atlas does not show it. The sentence says the producer travelled through South India and Ceylon looking at circuses before choosing two. Where a circus was found is not where the film was shot. Source.
