Hrithik Roshan and Katrina Kaif have just returned from a three-week-long Abu Dhabi schedule of Siddharth Anand's action thriller Bang Bang after shooting some heavy-duty chase sequences. The scenes were choreographed by Hollywood action director Andy Armstrong who has the mind-boggling gravity-defying stunts of films like Charlie's Angels, Planet of the Apes and The Amazing Spiderman 2 to his credit. Bang Bang, produced by Fox Star Studios, is an Indianised adaptation of the Tom Cruise-Cameron Diaz starrer Knight And Day.

A source present on the sets said, "Hrithik is in prime physical form and is keen to push the envelope. Despite fears of aggravating the head injury that he sustained during the film's first schedule that led to a surgery and a long recuperation, Hrithik insisted on doing all the action sequences sans a body double. Such action will be seen for the first time in Hindi cinema."

The actors flew in on May 19 and filmed across the Emirates, at the Corniche, Liwa Oasis, Hyatt Capital Gate Hotel, Qasr al Sarab, Emirates Palace and Yas Island. Bang Bang opens on Gandhi Jayanti, October 2.
