Kunal Kapoor reveals his massive transformation: "I had just six weeks to go from being..."

One of the exciting parts about being an actor is to physically transform for a role. However, this time around, it was challenging because about six weeks before we shot the action sequence that required me to be extremely fit, we had to shoot a scene where I am out of shape. So, I had just six weeks to go from being out of shape to looking very strong.

This action sequence required me to look physically intimidating, but lean. My trainer Samir Jaura, put me on a routine, for which I had to train twice a day. My day started with an hour of cardio and a training session and another weight-lifting session in the evening. We reduced my carb and salt intake, focussed on high-protein foods and cut out sugar from the diet.

I must say that Kunal is an incredibly dedicated and committed actor. He delivers more than you expect. I didn't think he would be able to get into shape so quickly because just six weeks before it, we had shot a sequence where he looked the complete opposite. I was shocked when I saw the transformation.

I've always been a big fan of pulp novels, and this is an edge-of-the-seat pulp entertainer. I think it's amazing how Amin has seamlessly brought a love story, a suspense drama and pulp fiction together.
