Milan Luthria's latest flick Once Upon A Time In Mumbaai is going to face a hit just a few days before the release of the film on July 30.

On Monday, Suleman Mirza, the adopted son of the alleged gangster late Haji Mastan Mirza, has filed a suit seeking ban on the release of the movie, which is supposedly based on the life of his father and fugitive don Dawood Ibrahim Kaskar.

Suleman has objected strongly on the portrayal of his adoptive father as a don in the film. He contended saying that the makers of the film cannot defame anyone in the name of freedom of speech and expression.

According to the suit, "As per the defendants, the movie is based on the life of anti-social elements like Dawwod Ibrahim and late Matsan. But, Haji Mastan was working for the poor people, to whom he was like a god father and his work has benefited many families".

Suleman further added that there was no order against Mastan to convict him in any registered criminal cases. Hence, no one can defame the reputation of his father by depicting him as a goon.

Ashok Sarogi, lawyer of Suleman, said that he has asked for a stay on releasing the film by an interim order.

Once Upon A Time In Mumbaai stars Ajay Devgn, Kangana Ranaut, Emraan Hashmi, and Prachi Desai in the lead roles.
