She shot to fame after some rival gangsters led by Arun Gawli gunned down her husband Ismail Parkar in a gang war in 1991 which led to a spate of brutal retaliatory killings from the Dawood gang at that time.Subsequently, Haseena was reportedly acting as the don39s Mumbai business head. Though officially she was not directly implicated in any underworld activities, it is believed that in parts of south Mumbai, nothing moved without her nod. This is not the first time Sonakshi will be starring in an underworld film. She played Dawood's love interest in 'Once Upon a Time in Mumbaai Dobaara!', which was said to be based on the life of the fugitive don."Haseena - The Queen of Mumbai" will roll out for shooting early next year. It will bring alive 40 years of Haseena39s life and is the emotional saga of a woman and what it meant to be Dawood Ibrahim39s sister.
