Kalki Koechlin recalled filming 'Zindagi Na Milegi Dobara' in Spain, saying, "We had these huge film stars like Hrithik [Roshan] and Katrina [Kaif] in a completely foreign country. When we shoot or go for a screening [here], there's security." "But in Spain, it was different. We walked on the cobbled streets and nobody bothered us...It was wonderful," she added.
