Like Sangathil paadadha Kavidhai(as a tune), Kodeeswaran magal as a story has many incarnations. The telugu original, presumably was the first. I learn now that Kalaignar's Raja-Rani is the original original. Besides, the movie made it to Malayalam(one of the priyadarshan assembly line products in late 80's-early 90's). Then,as is his habit, it made it to Hindi as Hungama recently *ing Akshay Khanna, Rimi Sen etc. Then it was re-made into Telugu(incredibly from the Hindi version) *Ing Prabhu Deva, Aarthu Chaabria etc.
