This is the first time ever a Flyboarding stunt was done in a Bollywood or Hollywood film. Hrithik Roshan became the first actor to do a flyboarding stunt in a film. Regarding the water sequences, the film's director Siddharth Anand revealed, "We can control the action we shoot on land, but while shooting at sea, you're at the mercy of the tide. Three days before the shoot, Hrithik started practicing the stunts for five-six hours daily. It took us eight days to shoot the sequences in water. For another water action sequence, Hrithik trained for four days, before the shooting. He learned to jet-ski with a speed boat pulling him along first. Then, an antiquated plane was brought in with an experienced pilot at the controls, so that it could be slowed down and speeded up at will."
The film's teaser got 2.33 million views within 24 hours on YouTube, making it the most watched teaser or trailer ever in the history of Bollywood at that time.
Hrithik Roshan went through a brain surgery to remove a blood cloth during the shooting of the film, as he had injured himself on the sets of the film while doing the stunts.
With the budget of Rs.160 crores, this is one of the most expensive Bollywood film ever made.
Even after the brain surgery, all the stunts were performed by Hrithik himself.
