Bollywood star Akshay Kumar says there were producers who suggested that "Airlift" -- his forthcoming action thriller based on evacuation of Indians from Kuwait during the Iraq-Kuwait war -- should be made as a documentary.

"Director Raja Krishna Menon was working on this script for four years. He has been closely associated with many of those people who were stranded in that situation. It has been a tremendous effort of my director to present the facts onscreen.

"But let me tell you this... when he approached several producers with the script, they suggested him to make it into documentary," Akshay said here.

Akshay said it was disappointing.

"This evacuation is such a big fact for our country, but the kind of response the director got of making a documentary, it was upsetting. I want that each and every Indian must watch this film 'Airlift', and feel proud of being an Indian," said the actor.

The film, releasing on January 22, features Nimrat Kaur.
