Sivakarthikeyan is likely to play a policeman in the new movie.
"We are teaming up again, but it's too early to talk about the film. I can't tell you if Siva will be seen as a cop, but he will be playing a very different role than before," Senthil told IANS.
Starring Sivakarthikeyan in the lead role, "Ethir Neechal" was produced by Dhanush and directed by Kumar.
One of the biggest hits of the year, "Ethir Neechal", which made on a moderate budget of under Rs.6 crore, minted over Rs.15 crore at the box-office.
The film also featured Priya Anand, but she is unlikely to star in the next film.
"We haven't zeroed in on the heroine yet. It will take some time because we are yet to start casting for the new film," Kumar said.
Meanwhile, Sivakarthikeyan, who has had five back-to-back hits, is busy shooting for Tamil romantic-comedy "Maan Karate".
