Sivakarthikeyan is now briskly shooting for his biggie 'SK21', directed by Rajkumar Periasamy. Meanwhile, the actor's next project, 'SK23', with ace maker AR Murugadoss was officially announced back in September. This film will go on the floors after SK wraps up his work in 'SK21'.

Now, fresh reports pour in that SK23 will be a film with one of the biggest casting coups in the industry. According to sources, Malayalam superstar Mohanlal and Bollywood actor Vidyut Jamwal are likely to be on board this movie. Notably, Vidyut Jamwal has already played the powerful villain in AR Murugadoss' industry hit, 'Thuppakki', starring Thalapathy Vijay.

Reportedly, Mrunal Thakur is in talks for the female lead and Anirudh Ravichander is likely to score the music for 'SK23'. The upcoming movie will be bankrolled by Sri Lakshmi Movies on a grand scale. It is expected to be a Pan-Indian action flick and a mega-budget entertainer.
