Aamir Khan, who is playing a negative role in Dhoom:3, has returned to the city to promote the project. The actor took a fortnight’s break from shooting Rajkumar Hirani's P.K., to work on the trailer of his next - Kill Dil - that is being produced by Aditya Chopra. A source says, "Aamir requested Hirani to wrap the schedule of his film early so that he could be in Mumbai in time for for the trailer launch (on October 30)." To make time for the project, the actor apparently worked overtime. "Aamir will resume shooting for the movie after Diwali now. The crew didn’t seem to mind his decision either, as they also got an unexpected break," says the source. Aamir was constantly in touch with Chopra, who had sent the trailer to him for his feedback. It is being converted to the Imax format and is scheduled to launch at the end of this month. Directed by Shaad Ali, Kill Dil also stars Ranveer Singh, Parineeti Chopra and Ali Zafar.
