Ajay Devgn released the trailer of his latest home production, Tanhaji: The Unsung Warrior, in Mumbai.

It will be the actor's 100th movie release, and sees him reunite with his Kachche Dhaage and Omkara co-star Saif Ali Khan.

Saif plays the antagonist to Devgn's titular military warrior, and they play off each other very well in the trailer.

Off screen, of course, Devgn and Saif share a warm relationship and it was evident at the trailer launch.

Rohit Shetty has always shared a close relationship with Devgn, making him centrestage in blockbuster franchises like Golmaal and Singham.

He made sure to be with the actor, as the latter announced his historic 100th movie.

Tanhaji: The Unsung Hero features a lot of combat scenes, with Devgn doing a different kind of action from what he has done in Rohit Shetty movies.

He talks about it in this video.

Devgn's real life wife Kajol doubles up as his reel life better half in Tanhaji.

What was it like working with her again?

Devgn gives his reply in the video below.

Saif Ali Khan plays Udaybhan Rathod, and he feels his character is 'crazy'.

He enjoyed the shooting process, and tells us why in this video below.
