And here it is again, this time with the amazing video with dancing on the rooftops of a moving train.
Quote:
"The video was filmed on top of the Ooty train (the Nilgiri Mountain Railway) in mountainous Tamil Nadu, southern India while actor Shahrukh Khan dances with model/actress Malaika Arora and other dancers. The film was directed by Mani Ratnam and photographed by Santosh Sivan. The choreography was completed in four and half days by Farah Khan.
No major back projections or post-production special effects were used in the music video. Malaika Arora, one of the performer recalls: "Would you believe it? Well, the "Chaiya Chaiya" song was shot exactly as you see it on the screen: No camera tricks, no back projection, no post-production special effects!""
