What does Thalaivaa have in connection with Nayagan and Baasha

There are comparisons being made between Vijay starrer Thalaivaa and Nayagan and even Baasha. But the director A.L.Vijay has said that, though the theme may be the same the content is totally different from those two movies.

While writing the script, the director was sure that he needed some big star but was not specific about Vijay. Ilayathalapathy happened to like the director's pitch about the script and the project immediately kick-started. 

He is happy with Ilayathalapathy's work on his voice and body language as his character goes through a marked transition. 

Director Vijay sums up Thalaivaa as a movie with a good story and a great star, and also one which would have both the Vijays' sensibilities in equal measure.
