or beard gives grittiness to the character. Hence, Khan is seen unshaven. Om Puri, Kirron Kher, Vivek Oberoi, Dia Mirza Puri was given suit vests to don throughout the film. Intentionally, all his pathani kurtas were washed by a dhobi to get the worn look, which he noticed. Kher received long tunic, long skirts, and shawls wrapped around her head to justify her as an Afghan. She was very involved with her outfits. She had her ideas that she shared with Narula and worked together on her looks. Oberoi was given a lot of dark jeans, t-shirts, sweaters, wind cheaters in navy blue, grey, olive green, and black leather jackets, all from Zara and H&M, while Mirza was given short skirts with jackets and work bags, in black formal work outfits. Filming Principal photography commenced in November 2008 in Philadelphia. A set was erected to shoot the replica of a terrorist attack. The subway tube scene was shot underground where the train was hired. Khan noted the cold weather conditions to an added difficulty in getting the pitch and tone right while delivering dialogues. The characters were shooting in sync sound. There were 80 people in the unit. Also during the shoot, Kapoor fainted on the sets owing to the cold weather. Some scenes were filmed in Brooklyn. A three-minute erotic scene between Khan and Kapoor (through the song "Rasiya") was requested to be removed from the film print by Kapoor for personal reasons. She'd agreed to shoot for it because it was integral to the script. In an interview with Press Trust of India, she was quoted saying: "“I've done kissing scenes earlier, but the lovemaking scene is explicit by my yardstick.” Khan flew down to India due to health reasons on 22 December 2008. D'Silva made an attempt to film in U.K. but cancelled due to lack of permissions and security issues. Filming took place in areas around Rajpath and Delhi Haat in February 2009. The song "Shukran Allah" was shot close to Humayun's Tomb with 2 lakh people witnessing the shoot. However, owing to the lead pair's popularity, there were a huge number of people who had come to see them especially. The areas of Jama Masjid and Janpath were always too high to shoot. Hence, barring a few shots, wide-angle shoots were cancelled enforcing recreation of scenes planned in Delhi for Mumbai between mid-March to April
