at heart and a bohemian gypsy by nature". Zoya had wanted to work with Kalki Koechlin ever since seeing her in Dev.D (2009) and That Girl in Yellow Boots (2011); she felt Koechlin would suit the character of Natasha because she had "the sense of comedy, but not over-the-top". Spanish actress Ariadna Cabrol was chosen for the role of Nuria because Zoya liked her work in the 2009 Spanish film Eloïse's Lover. Filming Principal photography began in June 2010 and took place in the United Kingdom, Egypt, Mumbai, and in Spain at Barcelona, Pamplona, Buñol and Andalusia. Cinematographer Carlos Catalan, who had worked with Zoya on Luck by Chance, wanted all three lead actors to appear tanned because he "didn't want everything glossed over" and wanted to make the film as realistic as possible. Kaif's introduction scene was shot on a nudist beach; during the filming, the crew asked beach-goers stay out of the frame to avoid objections from the Central Board of Film Certification. The La Tomatina festival of Buñol was re-created for the song "Ik Junoon"; almost sixteen tons of tomatoes worth were flown in from Portugal for the scene. A scene involving a kiss between Roshan and Kaif was filmed despite the couple's reluctance to do so. The filming of the flamenco song "Señorita" took place in Alájar, a town in the province of Huelva. The crew warned local residents about the song's volume because the scene was filmed at night. On the third day of filming, locals dressed in costumes attended and the mayor of Alájar joined them. The climax of the film, which features the running of the bulls, was filmed at Pamplona. The final schedules were at Vashi and Alibag in Mumbai in December 2010. Soundtrack Composer trio Shankar–Ehsaan–Loy, who had worked with Farhan Akhtar in Rock On!! and Karthik Calling Karthik (2010), composed the soundtrack for the film. The lyrics were written by Javed Akhtar. The composers engaged María del Mar Fernández, a Spanish flamenco singer, to perform the vocals on "Señorita"; her film-singing debut. The song is also the singing debut of Deol and Roshan, who sang it along with Farhan Akhtar. Marketing The trailer of the film was revealed with the prints of Ready which released on 3 June 2011, and was released online on 15 May 2011.
