According to reports, Nayanthara was rumoured to be roped in as the second leading lady in the film.
“Rakul Preet is the only female lead in my film with Mahesh sir,” Murugadoss wrote on his Twitter page on Friday.
Tipped to be a stylish action-thriller, the film features Mahesh in the role of an intelligence officer.
The film also stars actor-filmmaker S.J. Suryah as the antagonist, apart from R.J. Balaji, Dheepa Ramanujam and Priyadarshi Pullikonda in supporting roles.
The film is being jointly produced by Tagore Madhu and N.V. Prasad.
