Actor-lyricist-singer Arunraja Kamaraj shot to fame when he penned the lyrics to Neruppu Da in Rajinikanth's Kabali directed by Pa Ranjith. The song became a sensational hit and even ended up becoming the title of another film. With Rajini and Ranjith coming together once again for Kaala, Arunraja has been roped in to write a song for the film.

Talking to CE, he says, "While I can reveal that I've written a song for Kaala, I can't speak much about it at the moment. I'm not sure if it's the introduction song or if I'll sing it. Hopefully there will be official confirmation soon."

Meanwhile, Arunraja is also busy with the pre-production works for his directorial debut -- a film on women's cricket. "We've got a good response for our casting call. But I'm yet to call anyone for in for auditions. Once the pre-production works are complete, we'll zero in on the actors." he adds.
