Siddharth Anand's "Bang Bang" is reportedly witnessing a tense situation between co-stars Hrithik Roshan and Katrina Kaif.

The actors who started off on a strong note while shooting the action film have allegedly fallen out and are giving each other cold shoulder. Roshan and Kaif are reportedly ignoring each other on the film's sets and hardly acknowledge one another, reported One India.

The "Dhoom 3" actress is acting quite indifferent in the recent days and only keeps to herself. She is said to be hardly mingling with Roshan and limits herself to her vanity van after her shot are over. As a result, the duo has not been seen hanging out with each other like before, according to the website.

Report of tension between the duo is quite shocking since earlier this year reports were abuzz of the strong bond the actors shared after Roshan broke up from his long-term wife Sussanne Roshan. The duo reportedly had a good time during their Manali shooting of "Bang Bang" and were seen often engrossed in deep discussions over films and life.

Also, since the "Krrish 3" actor has worked with Kaif previously in "Zindagi Na Milegi Dobara," the report of the actors turning indifferent is worrisome.

However, despite the reports of strain between the actors, the shooting of the film is going strongly. On Tuesday, a roof-top cafeteria was created in Filmcity where a song of the film was shot till early morning.

Meanwhile, the film is set to shoot some important action scenes in Abu Dhabi. The sequences will be choreographed by Andy Armstrong who recently designed stunts for the soon-to-release Hollywood flick "The Amazing Spider-Man 2."

"Bang Bang," which is set for release on 2 October this year, is reportedly pacing against time to meet its deadline as a large part of the film still remains to be shot.
