Every male actor wants to try a female role in their acting career. Some do it as part of a song, and some other do it through cross-dressing. Aanazhagan was Prashanth’s try at a cross-dressing role. To be honest, he did succeed a bit in carrying the part.
Nillatha Vennila is an interesting song. It doesn’t follow any set rhythm pattern that you are used to in any Tamil song. The song just flows like a river through the voices of Ilaiyaraaja and Swarnalatha. A masterpiece that never made it to the screen.
