After the highly successful soundtrack of Mersal, lyricist Vivek will be joining hands with AR Rahman for two more projects --Vijay's Sarkar and Sivakarthikeyan's untitled sci-fi film that's known as SK 14.  The lyricist took to Twitter to break the news.

The shoot of Sarkar, also starring Keerthy Suresh, Varalaxmi Sarathkumar and Yogi Babu is expected to be wrapped up in August and the Sun Pictures production venture is scheduled to hit the screens on Diwali. Sivakarthikeyan, meanwhile, is simultaneously shooting for the yet-to-be-titled science fiction, co-starring Rakul Preet and Isha Kopikkar, and director Rajesh's romcom, alongside Nayanthara.
