Hrithik Roshan and Jr NTR kicked off a fun off-screen 'war' ahead of War 2 with billboard exchanges. Hrithik teased Jr NTR with a banner that read, "Naatu Naatu as much as you want but I'm winning this war." War 2, directed by Ayan Mukerji is set to release on August 14. The film also stars Kiara Advani.
