Filming started in Delhi on 4 February 2010, the same day the production company announcement was made. Singh was very nervous about his first day but was eventually proud that his first scene only took three takes to shoot. An 18 February article by Minakshi Saini for the Hindustan Times' entertainment supplement HT City reported that during the previous day's early morning shoot in West Delhi's Subhash Nagar, Singh's newcomer status led many to speculate on whether he was Ranbir Kapoor, Ranvir Shorey or even Riteish Deshmukh. Police officers were eventually called in to secure the set from curious onlookers, however some expressed discontentment at having to be out in the cold despite both lead actors being virtual unknowns. The film features a kiss between the lead actors, which only necessitated a single take. Reportedly, Singh accidentally hit Sharma while filming an undisclosed intense scene. Other than Subhash Nagar DDA Market, locations in Delhi include Janakpuri, Delhi University, North and West Delhi, Ring Road, Mehrauli Farms and Akbar Road. Some scenes were also shot in director Maneesh Sharma's almamater, Hans Raj College in University campus. The film was additionally shot in Mumbai in March and Rajasthan in April.
Prior to the film's release, Anushka Sharma referred to it as her \"best film till date\". Band Baaja Baaraat's trailer and official website were both unveiled on 19 October 2010, a couple of months before the theatrical release. In addition to the film's synopsis and trailer, the website initially also contained five wallpapers and a press kit for visitors to download. The number of available wallpapers later grew to twenty-five and the website eventually allowed visitors to send e-cards to their acquaintances, with the virtual cards dubbed \"Band Baaj-O-Grams\". A number of contests were organized by Yash Raj Films, including one where the company, along with partners Radio Mirchi and BIG Cinemas, offered the winning couple a free wedding in December, in time for the film's release and supposedly planned the film's heroes, and another in which a couple would win a trip to Switzerland and visit the filming locations of the various Yash Raj Films productions to have been shot there. In addition to the website, Yash Raj Films also had regularly updated official pages on Facebook and Twitter and a Blogspot blog in an effort to reach the widest audience possible. The company finally uploaded a number of videos on their YouTube account, including the trailer but also several videos promoting the songs \"Tarkeebein\" and \"Ainvayi Ainvayi\".
The project began shoot by the end of May 2013 and shot in Hyderabad with Padam Kumar, head of Yash Raj Film's operation in South India, being appointed the creative producer on the project. Scenes were shot predominantly in a swift schedule in Chennai, completing most portions of the shoot with little publicity. The team then shot a schedule in early September 2013 in Mysore in a set erected near Lalith Mahal Hotel, with rain partially disrupting progress. Although it was planned as a bilingual it was completely filmed in Tamil only and was later dubbed in Telugu while the songs and climax scenes were individually shot in both the languages. 076b4e4f54
