In 1999, Chawla collaborated with Shahrukh Khan and Aziz Mirza, and formed her own production company along with them, which was named Dreamz Unlimited. Their first productional venture was Phir Bhi Dil Hai Hindustani (2000), which proved to be the thirteenth highest grosser of the year, but failed commercially, it was followed by Aśoka (2001), which was also a commercial failure, and it's commercial failure attributed to a setback. The last feature which Dreamz Unlimited produced was Chalte Chalte (2003), which was a box office success, but after this they parted ways, due to a conflict between the workers.
