Hrithik Roshan is shooting "Krrish 3" amid tight security and feels it is totally justified as it will help in guarding his superhero image till it is revealed on Diwali later this year.

"I feel that the security is totally justified because when you create something, you want it to be presented in the way it is supposed to. I often get tired on the sets and if someone takes a picture of me like that, it's not fair as it would destroy the feeling of a superhero," he told media during an interaction Thursday. The journalists gathered at his Juhu residence to celebrate his 39th birthday.

For the actor, "Krrish 3" has been one of the toughest experiences.

"I know, I say this for all my films, but this film has been one of the toughest challenges, which is still not over," he said.

Being directed by his father Rakesh Roshan, the film, which also stars Priyanka Chopra, Kangna Ranaut and Vivek Oberoi, has been in the making for five years.

The earlier two versions - "Koi... Mil Gaya" and "Krrish" - were very successful and the actor says the fate of "Krrish 3" will be decided when it will come out on Diwali this year.

"We have been after this film since the past five years. The special effects are still left. This Diwali we will come to know how victorious we have been," he said.

"The expectations from the film motivated us to go beyond boundaries. It has gone beyond our imagination now," he added.
