The film, described as a Bollywood version of Brokeback Mountain, will be shown at Finnmark Pride in Norway, attended by lead actors Kapil Sharma and Yuvraaj Parashar.
Actor-writer Sharma said: "I am overwhelmed as travel is my passion. In fact during school days geography was my favourite subject and whenever I studied about tundra, igloos, reindeer, eskimos, I always dreamed of going there.
"This film has made my dreams come true and has also won awards and acclaim at Sydney, Greece, Cologne, Dortmund, London, New York and Tel Aviv."
Parashar, a former beauty pageant winner, added: "I am very excited to go to Finnmark but only thing that I am worried about is, will I get vegetarian food without onion and garlic there? Maybe I will have to carry one week's worth of food stock with me.
"The pride will include culture, music, politics and short hikes. Finnmark is the northern region of Norway where there is zero pollution, reindeer sledges and no exhaust or engine noise."
Dunno Y... Na Jaane Kyun also stars Zeenat Aman, Kapil Bedi, Helen and British actress Hazel.
Finnmark Pride takes place from August 31 to September 9.
