Box office Jaan-E-Mann opened in nearly 1,200 screens worldwide. The film faced stiff competition from
Don – The Chase Begins Again which also released on the same day. The film opened to a 40% response. The second day saw a huge drop in the collections, due to the Diwali celebrations. According to
boxofficeindia.com, the collections jumped to 70%, but fell again to 50%. The film has done very well in the smaller centres in India. Pranab Kapadia, the UK distributor of
Jaan-E-Mann said "
Jaan-E-Mann's figures have picked up dramatically in Britain. Although the film grossed a mere £18,000 on its opening day, the film has experienced a remarkable upswing, grossing £40,000 on Monday and £60,000 on Tuesday. The audience and critics reception has been overwhelming."
Critical reception Taran Adarsh of
Bollywood Hungama gave the film 3.5 out of 5, saying "On the whole, JAAN-E-MANN balances humor and emotions beautifully. In fact, it's a BIG film in all respects -- right from its cast to the extravagant sets to the lavish making, besides, of course, unadulterated entertainment it has to offer. At the box-office, the Diwali and Idd holidays will prove bountiful for the film and add to the big returns. Business-wise, JAAN-E-MANN should fare best at multiplexes and also at major centres, besides Overseas. But its business at comparatively smaller centres, where masala films dominate, is bound to be affected by DON's presence. However, if the strong word of mouth catches on, the business at smaller centres will add to its booty." Poonam Joshi of
BBC.com gave the film 4 out of 5 stars, writing "Jaan-E-mann simultaneously parodies the worst elements of Hindi cinema, while exulting in the best that Bollywood has to offer, making for an unexpectedly original and entertaining film."
Raja Sen of
Rediff.com gave the film 3 out of 5 stars stating "In the end, what echoes in your ears as you leave is Akki's thick, goofy he-he-he laugh. It's the best thing in the film." Conversely, Namrata Joshi of
Outlook India called the film "A mish-mash—a twisted love triangle but even the inventive narrative doesn't take it very far."
Vincent Musetto of
New York Post gave the film 1 out of 5 stars, writing "We keep waiting for one of those outlandish musical treats to bring some life to the clichd script. Kunder throws in a few breaks, but they're tepid and brief." == Nominations ==
