There was tight security reportedly around the sets of 'Krrish 3', shot at various locations across the metropolis including Film City, and the makers were cautious as they did not want to give away anything before its release this Diwali.
On a query, Hrithik told reporters here, "I feel that the security is justified because when you create something special you want it to be presented the way it is suppose to be and at the right time."
"Krrish has a certain superhero image. Sometimes when Iam resting on the sets and someone takes a candid picture then the whole image of a superhero can be ruined," he said.
"I may say this for all my films but Krrish 3 is really my toughest challenge. The challenge is still not over," he said.
Directed by his father Rakesh Roshan, the film stars Hrithik, Priyanka Chopra, Kangna Ranaut and Vivek Oberoi in lead roles.
