Sivakarthikeyan is on a roll as he is experimenting with various genres and taking up challenging roles. His body transformation to play a soldier in his new biggie, 'SK21', is the talk of the town now. Meanwhile, the actor is all set to start his next project tentatively titled 'SK23'.

We all know that Sivakarthikeyan is set to work with ace director AR Murugadoss in his 23rd movie after the completion of 'SK21'. Now, it is said that the filming for 'SK23' will begin tomorrow. The production is funded by Tirupati Prasad under the banner Sri Lakshmi Movies. We are yet to learn when Sivakathikeyan is joining the shoot.

Sensational actress Mrunal Thakur is likely to be the project's leading lady while the makers are in talks with Mohanlal and Vidyut Jammwal to play pivotal roles. Anirudh Ravichander is the frontrunner to compose music. On the other hand, the first look and title teaser of 'SK21' is slated to be unveiled on the actor's birthday eve, February 16th at 5 PM.
