Actor Biju Menon is the latest addition to the ensemble of Sivakarthikeyan-AR Murugadoss' next, which is interchangeably called SKxARM and SK23.

Recently, Vikranth and Vidyut Jammwal joined the star cast, with the latter roped in to play the antagonist.

Notably, SK23 will be Sivakarthikeyan's first collaboration with director Murugadoss, although the filmmaker had previously written the former's sports-comedy film Maan Karate, directed by Krish Thirukumaran. The team recently began shooting the second schedule of the film.

Produced by Prasad NV under the Sri Lakshmi Movies banner, the film's technical crew includes cinematographer Sudeep Elamon, editor A. Sreekar Prasad, and music director Anirudh Ravichander.

Sivakarthikeyan also has Amaran, slated to be released on Diwali. It is an action film directed by Rajkumar Periasamy and bankrolled by Kamal Haasan's Raajkamal Films International. Amaran, starring Sai Pallavi as the female lead, is based on the life of Major Mukund Varadarajan.
