The success of Chalte Chalte has brought Khan's production house Dreamz Unlimited -- in partnership with director Aziz Mirza and Juhi Chawla -- back in business.

The company suffered considerable financial losses after the failure of their earlier two films, Phir Bhi Dil Hai Hindustani and Asoka.

Khan does not regret it. "I don't think we did anything wrong in the earlier films. Our ground rules for filmmaking didn't change just because the other two films didn't do well. This time too [with Chalte Chalte], we did exactly what we wanted.

"Like PBDHH and Asoka, we marketed it cheap to make sure distributors didn't suffer any losses. Thankfully, we weren't wrong. Both the audience and the media were kind to us. It is the kind of film everyone felt kind toward, since everyone has fights at home with the spouse. So far it is the biggest hit this year. As a producer, this is a new experience for me."
