Katrina and Hrithik busy shooting for 'Bang Bang' in Shimla

Bollywood superstars Katrina Kaif and Hrithik Roshan are on a role and busy shooting for their movie 'Bang Bang'.

Recently they have been spotted in Shimla while shooting for this action thriller.

Katrina looks adorably cute sporting these winter clothes.

'Bang Bang' is the official remake of Tom Cruise Cameron Diaz starrer 'Knight and Day'. It is scheduled to release on 2nd October this year.

Shooting for the film began in June 2013. While shooting for the film in Phuket, Thailand, Hrithik Roshan leapt from a height of 30 feet and sustained an injury while falling into a water body.

Later he had to go through an operation in Mumbai to remove a blood clot from his brain. He was advised by doctors to take rest, which delayed shooting of the film.
