WATCH: Indian skipper Dhoni got angry with actor Sushant Singh Rajput

Actor Sushant Singh Rajput, who will be seen essaying the celebrated Indian cricketer Mahendra Singh Dhoni's life for his upcoming film "MS Dhoni: The Untold Story" said during their interaction, he saw Dhoni losing his cool for the first time.

Recalling his phase while interacting with Dhoni to get into the skin of the character Sushant says, "For the first time I have seen Dhoni losing his cool. First two to three days I asked him some questions and he answered them calmly. Then he said you ask lot of questions let me come back. I was just asking him one question in different ways again and again."

Adding to this Dhoni said: "He (Sushant) used to ask one question repeatedly and if he gets similar answer then he used to believe that I am being honest and then he used to go to next question."

"It was a bit awkward initially to speak about yourself. After 15 mins you get bored talking about yourself and I was like I need a break, I am going," he added.

Dhoni, has co-produced the biopic, which stars Sushant Singh Rajput in the titular role.

Sushant said more than pressure he was excited to be part of this project.

He said, "It was more excitement than pressure. In 2007 after too much of hard work we clicked a picture with him. He is one person who seriously has enormous respect for everyone. I look up to him. To get an opportunity to know his inside story gave me lot of excitement and not pressure."

He added, "There are films in your career which you do it with full honesty and you end up being a good actor but there are very rare films that you do and you end up being a good human being and this is one of them."

"MS Dhoni: The Untold Story" also stars Anupam Kher, Bhumika Chawla, Rajesh Sharma and Kiara Advani. It is set to release on September 30.
