Actor Saif Ali Khan is currently busy shooting for the historical movie ‘Taanaji: The Unsung Warrior’. The movie is based on the Battle of Sinhagad in 1670, which was fought between Tanaji Malusare, a commander in Chhatrapati Shivaji Maharaj’s army, and Udaybhan. The former sacrificed his life to recapture Sinhagad Fort from the Moghuls. While Ajay Devgn will play Tanaji, Saif Ali Khan will play the antagonist in the movie.
