It is one of the most beautifully shot songs but shooting Gerua on Shah Rukh Khan and Kajol in the scenic but cold climate of Iceland was no cake walk for the Dilwale team.
Giving a sneak peak into the making of the song, SRK-Kajol explained how they defied the cold to capture the stunning beauty of the place for their romantic number.
For those wondering what a broke plane was doing in the song, SRK said it was already there in the middle of nowhere and they just decided to include it in the movie.
"It was surreal. Half broken plane in the middle of nowhere.. We did not discover it. Rohit did not break it. It was just like that and the legend has it that the pilot crash landed there and saved everybody," Shah Rukh said.

"People go and romance in front of the waterfall and green fields and we decided to do 'ulta' and go behind the waterfall. We were drenched and she saved my life.," said the actor explaining how Kajol got hold of him while he was about to take a tumble near the waterfall.
The actor said Kajol fooled her kids that she could walk on the water as they shot a scene on the shallow lake.
Dilwale is set to release on 8 December, 2015 along with Sanjay Leela Bhansali's Bajirao Mastani.
