Kaththi, the Vijay starrer that is being directed by A R Murugadoss is currently being shot in Chennai. Samantha pairs up for the first time with Vijay and the film is being produced by Lyca Productions.

Anirudh is the music director of the film and it has been said that Vijay will lend his voice for one number. Meanwhile there were rumors that Dhanush was penning the lyrics for Vijay's song but that was put to rest as a rumor.

For the latest update on the film, Anirudh says that Kaththi is really shaping up well. He states in his microblogger, "#Kaththi shaping up really well! Hope you all love it as much as we do :)"

With the film in a fasttrack mode, the expectations are also warming up pretty fast as the film gears up for a Diwali 2014 release.
