Yash Raj Films announced the then-untitled project on 5 August 2010. Ali Abbas Zafar, who's been an assistant director on a number of Yash Raj Films productions such as Jhoom Barabar Jhoom, Tashan, New York and Badmaash Company, makes his feature writing and directing debut with this film, which has been described as a comedy of errors by lead actor Imran Khan. After Band Baaja Baaraat, this marks the second Yash Raj Films production in a row to be helmed by a first time director who was previously an assistant director. Zafar is originally from Dehradun, where much of the story is set. After years of working with Yash Raj Films, he submitted three love stories to producer Aditya Chopra, who eventually greenlit Mere Brother Ki Dulhan, enabling Zafar to start writing his 150 page long script. Ali Abbas Zafar is an alumnus of The Players, the acclaimed theater society of Kirori Mal College, University of Delhi, where he acted in different plays including an adaptation of William Golding's Lord of the Flies.
Like many Bollywood films, Mere Brother Ki Dulhan has suffered allegations that it is a rip-off of an American film even before filming wrapped. According to these sources, the film rips off Dan In Real Life, in which Steve Carrell's character also falls in love with his brother's girlfriend (played by Dane Cook and Juliette Binoche respectively). The film has also drawn comparison to an earlier Yash Raj Films production, Mere Yaar Ki Shaadi Hai.
Imran Khan and Katrina Kaif play the romantic leads in the film, and their involvement was announced in the same press release as the initial production company announcement. this is the first time they've been paired together. They were initially to star together in 7 Days In Paris for director Sanjay Gadhvi, but the film has been indefinitely postponed. some media publications have alleged that their casting was an attempt by Yash Raj Films to end a recent string of box-office flops and disappointments. While this is Imran Khan's first movie for Yash Raj Films, Katrina Kaif had previously worked with them (and then assistant director Ali Abbas Zafar) on the critical and commercial hit New York. She was able to take the role thanks to the postponement of Dostana 2 to which she was already committed. Her role has been reported in the media as different than characters she'it down after initially accepting it. It was then given to Ali Zafar (no relation to the director), an actor who'd received rave reviews for his debut film Tere Bin Laden and who confirmed his participation via his Twitter account. A popular singer, Zafar will also perform his character's singing in the film and described his casting as "a dream come true" and his role as a "parallel lead role". The film additionally stars a new actress Tara D'Souza who is a former Kingfisher model.
On 17 October 2010, several media outlets reported on the casting of Preity Zinta in an unspecified "glamorous role". The actress however quickly denied the report on her official Twitter page.[18
Filming started on 25 September 2010 and was scheduled to be completed by November. The film started shooting in Delhi and Pataudi, before moving on to Chandigarh, Agra, Dehradun, Mussoorie, Haridwar, Dhanaulti, Punjab and Himachal Pradesh for a total of 45 days of filming in northern India and finally finishing the film in Mumbai. Juggling between this film and the final shots of Tees Maar Khan and Zindagi Na Milegi Dobara, Kaif joined the shoot on September 27.
A bloody incident happened very early in the shoot, on September 29, while the crew was filming at Pataudi Palace. The scene being shot, comic in nature, involved Imran Khan pulling Katrina Kaif towards him while pointing a gun towards other cast members. However, Khan miscalculated the move and instead sent the gun barrel crashing into Kaif's nose, causing it to bleed profusely. I am pretty bruised but the staff feels it's good luck for the film. But it was a funny scene so I think it was worth it" and "Please don't make it seem as if Imran was careless or something. These things happen. We were shooting one of the really madcap scenes where the actors' limbs acquire a life of their own. Imran's hand landed on my face" Another incident of sorts was reported by the media in early October and involves an emotional scene where Kaif's character slaps Khan's. Kaif would have been content to slap Khan once, however he insisted on sixteen takes so that the director would have a variety of slaps to choose from. Kaif was involved in another accident a few weeks later while filming in Nabha. Her hair got caught in a fan, and it was thanks to co-star Ali Zafar's quick action that the incident didn't turn more serious. Zafar and a spot boy named Raju did however sustain minor injuries and bruises. The film's title, Mere Brother Ki Dulhan, was revealed on October 2 along with a few promo pictures. Ali Zafar stated that Kaif promised him that if the film made over 600 million at the box office, she would do a music video with him.
