Band Baaja Baaraat was released worldwide on 10 December 2010, and proved to be a commercial success, despite initial competition from No Problem and Tees Maar Khan.

A Tamil remake titled Aaha Kalyanam also produced by Aditya Chopra under the Yash Raj Films banner, starring Nani and Vaani Kapoor in the lead roles was released on 21 February 2014.

The next day, Bittoo brings a video of Shruti's dance the previous night to impress her, and she ends up sharing her plans to start a new wedding-planning venture, called Shaadi Mubarak.

[8] Director Maneesh Sharma, with whom she's been great friends since her first film, said that the model-turned-actress was a very feisty person, and a natural actress who didn't like doing multiple takes.

[9] The male lead was given to Mumbai-native Ranveer Singh, a complete newcomer with no prior acting or modelling experience whatsoever, who impressed producer Aditya Chopra so much that he cast him after his first audition,[10] signing a three-film contract with the actor.

[11] Singh, who took acting classes,[12] and hung out at Delhi University prior to shooting said about his casting "I’m the first solo hero Yash Raj is launching.

[11] 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.

[17] The assistant directors for the film were Akshat Kapil and Rohit Philip who'd previously held the job on Aaja Nachle (2007) and Do Dooni Chaar (2010) respectively.

The various dance sequences were choreographed by Vaibhavi Merchant, who has previously worked on countless films including such hits as Lagaan (2001), Devdas (2002), Veer-Zaara and Swades (both 2004).

The lyrics to the various songs were written by Amitabh Bhattacharya and playback singers include Sunidhi Chauhan, Benny Dayal, Shreya Ghoshal, Natalie Di Luccio, Himani Kapoor, Harshdeep Kaur, Labh Janjua, Shrraddha Pandit, Master Saleem, Sukhwinder Singh, Amitabh Bhattacharya and Salim Merchant.

The soundtrack was revealed on 19 October 2010, at the Yash Raj Studios in Andheri, Mumbai,[23] and was commercially released on 3 November[24] with a launch event happening at the Reliance TimeOut store in Bandra.

Critical reception for the soundtrack was mixed-to-positive, with "Ainvayi Ainvayi" receiving particular praise (SawfNews even stated that one would "probably want to see the movie just for this song"[26]) and agreeing that the album was a superior effort than the composing duo's previous solo soundtrack for Teen Patti (2010), while several criticized the track "Dum Dum" and lamented the similarity to previous Salim–Sulaiman scores.

[27] Prateeksha Khot of Bolly Spice only truly disliked "Dum Dum" and praised the "unconventional" lyrics by Amitabh Bhattacharya, but felt the album failed "to live up to the expectations generated by the initial tracks" and criticized the similarities with previous Salim-Sulaiman efforts such as Rocket Singh: Salesman of the Year (2009) and Aaja Nachle (2007).

[28] The Economic Times writer Ruchika Kher gave a positive review, describing the album as a "fun-filled soundtrack" and noting the similarities between "Tarkeebein" and compositions by A. R.

[29] Music Aloud also published a positive review, noting that while the soundtrack wasn't Salim–Sulaiman's best, it was still "a definite winner with some fantastic tracks".

Tuteja described the music as "one of the better soundtracks that one has heard from the house of Yash Raj Films in the last couple of years", "one of the best works of Salim-Sulaiman" and "much more than just a regular fun album".

[33] Band Baaja Baaraat's trailer and official website were both unveiled on 19 October 2010,[34] a couple of months before the theatrical release.

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".

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.

[38] The incident occurred on Kingfisher Airlines flight IT 331 from Mumbai to Delhi, where both Singh and Anushka Sharma were travelling in business class to promote the movie.

The ensuing argument grew so heated that the cabin crew had to intervene and both parties went to the police station upon arrival and stayed there for over an hour and a half, eventually sorting the matter out amicably without lodging any complaints.

Taran Adarsh of Bollywood Hungama gave it 4/5 stars commenting, "Thankfully, Band Baaja Baaraat works on every level.

The writing is crisp, the execution of the material [director: Maneesh Sharma] is worthy and the lead actors [Anushka, Ranveer] steer the film to the destination smoothly.

Pankaj Sabnani of Glamsham gave it 4.5/5 stars and wrote, "There's an interesting blend of humour, drama and romance in the film.

Sonal Dedhia of Rediff gave it 3/5 commenting, "On the whole, Band Baaja Baaraat is a refreshing film—very different from the usual romantic comedy movies we're so used to.
