Earlier, we reported that AR Murugadoss is directing the twenty third film of Sivakarthikeyan, with Rukmini Vasanth as its female lead. The latest development is that Malayalam actor Biju Menon is part of the film, according to a Times of India report. The actor told TOI, "I am going to be part of the film. It's a massive project. I have given dates spanning almost a year. I can't reveal more now, but my role will be there throughout the film."

The film, tentatively titled SK 23, reunites Maan Karate co-writer Murugadoss and star Sivakarthikeyan, and marks the first time the former is directing the latter. Production on the film is underway.

It has been 14 years since Biju Menon's last Tamil film, Porkkalam. The actor has since been an active part of Malayalam cinema. His last Malayalam release was Thundu, and he will next be seen in Nadanna Sambhavam with Suraj Venjaramoodu. Murugadoss, meanwhile, is doing a project with Salman Khan in the lead and Sajid Nadiadwala as its producer.
