Cricket icon Mahendra Singh Dhoni will launch the trailer of Bollywood biopic "M.S. Dhoni - The Untold Story", across three cities.

Dhoni will be travelling to Delhi, Jalandhar and Mumbai to launch the trailer of the movie, in which Sushant Singh Rajput steps in to play the real life cricket star.

The makers of the film are yet to finalise the venues in the three cities where Dhoni will launch the much-awaited trailer.

"Dhoni is a sensation across the country. He has a huge fan following, and what better way to launch the trailer than with the fans across various cities. We are now to take the very first glimpses of 'M.S. Dhoni - The Untold Story' for audiences in Jalandhar, Delhi and Mumbai over two days,” director Neeraj Pandey said in a statement.

Produced by Arun Pandey and Fox Star studios, the film will be releasing on September 30.

Sushant has toiled hard to play Dhoni, and undergone serious training for the role besides donning a hairstyle akin to that of the cricketer.

The movie also stars Anupam Kher, Bhoomika Chawla, Kiara Advani, Herry Tangri and Disha Patani.
