Sushant, 30, who was praised for playing ace cricketer M.S Dhoni in the film "M.S. Dhoni: The Untold Story", said: "After 10 to 15 years, I will work on my own biopic."
He was speaking to media at the Van Heusen and GQ Fashion Nights 2016 on Sunday here.
About the show, Sushant said: "It is a great experience and I'm feeling great in this outfit by Shantanu & Nikhil. The thought behind the collection is amazing."
Titled Kashmiriyat 1990 by the popular fashion designer duo Shantanu and Nikhil Mehra, the collection was inspired by the tribesmen of the valley.
Other Bollywood celebrities like Hrithik Roshan, Anushka Sharma, Mandira Bedi, Yami Gautam and Prateik Babbar were also present at the menswear fashion event.
Sushant also spoke about his much-awaited film "Raabta", which has been in news for his chemistry with his co-star Kriti Sanon.
"'Raabta' will be released next year. I am working on it. I hope the film gets appreciated like my last film on Dhoni," he said.
