The first song of Shah Rukh Khan and Kajol-starrer "Dilwale" will be released on 18 November, and reports suggest the song, titled "Gerua", is the most expensive song video in the history of Bollywood.

It has been reported that the video has been shot in the exotic locations in Iceland, coupled with a lot of special effects, making it the highest-budgeted song ever.

"The special effects in 'Gerua' are amazing. It is something that hasn't been attempted in Bollywood before. A lot of money was spent on making sure this song blows everyone's mind off," Bollywoodlife quoted a source as saying.

The report also said both Shah Rukh and "Diwale" director Rohit Shetty just wanted to make the film's first song video grander than ever and did not bother much about the cost.

Shah Rukh and Kajol will be seen romancing in the song "Gerua", and thus, there has been a lot of frenzy regarding the track.

Directed by Rohit Shetty, "Dilwale" is one of the biggest and most-awaited flicks of this year. Along with SRK and Kajol, the film also features Varun Dhawan and Kriti Sanon.

The film is slated for release on 18 December.
