in winter, Kartik ends up wearing cotton shirts and other summer outfits for the scenes while he's shivering inside,' says a production hand, adding, 'The days are windy. There's cold breeze and less sunshine but the entire cast has to wear light clothes for six-seven hours a day and make it look like the weather is pleasant.
