Rangbaaz, tentatively scheduled for release in coming December, revolves around the story of a con artist, Mengal told Images.
He said that though it is not a love story, the film does retain some element of it. "But it is not your usual formula film," Mengal clarified. "It is an experiment; let's see."
Model and actor Sara Bhatti, who is playing the lead in the film, said the character she is playing is "very strong".
"It is the main reason why I chose to do [this film]. She is her own hero," Bhatti told Images.
Bhatti was in the news recently for her divorce with Mikaal Zulfiqar after six years of marriage. The couple have two daughters.
Other than Bhatti, the cast includes Dubai-based model Essam Ali and Zhalay Sarhadi as well as veteran actors such as Sajid Hassan, Shafqat Cheema and Asif Khan, among others.
