Rarely do top actors come forward to do a cameo or an item number in a film where they do not play the lead.
And in Nayanthara’s case, she has only done such appearances in films of Rajinikanth (Kuselan, Sivaji) and Ilayathalapathy Vijay (Sivakasi). Remember that when director Rohit Shetty approached her to do a special item song with Shah Rukh Khan in Chennai Express, she politely refused.
But when Dhanush approached her to do this song Sathiyama Nee Enaku .. in Ethir Neechal, she decided to make this unusual choice without batting an eyelid. The director of the film Durai Senthil Kumar says that Nayan did not make any unreasonable demands and all she wanted to be clear was the placement of the song and importance of it in the film!
However Nayanthara is happy that her special appearance has not only clicked with the masses but worked big time for her. Remember, Ethir Neechal is her first film in Tamil, three years after her last release Boss Engira Baskaran.
The kuthu song Sathiyama Nee Enaku has become an instant hit and the audiences are clapping for it. Durai Senthilkumar the director and lyric writer of the song says it is all because of Dhanush and his chemistry with Nayan who did the song free!
Sify observation- Did the yellow dhavani do the magic? There is a general feeling among Tamil film makers that all item songs with yellow costume becomes a hit!
