Sivakarthikeyan is currently working on AR Murugadoss’ next, which is tentatively referred to as SK x ARM or SK23. The much-anticipated film is the maiden collaboration between Sivakarthikeyan and Murugadoss in the capacity of actor and director. They have earlier collaborated on Maan Karate, which was backed and written by Murugadoss. It has been raining cast updates from the project, and the latest announcement is that National Award winner Biju Menon has joined the project. The makers, Sri Lakshmi Movies, released behind-the-scenes footage showing Menon in the shooting spot where Murugadoss was running a tight ship. The actor joins Vikrant, Vidyut Jammwal, and Rukmini Vasanth in the film.
