Sanober Shaikh, daughter of late Hussain Ustara, has filed a civil suit in a Mumbai court to stop the release of 'O'Romeo', alleging that it's an unauthorised biography of her father. The lawsuit names film producer Sajid Nadiadwala, director Vishal Bhardwaj, and journalist-author Hussain Zaidi as defendants. The film could cause "irreparable injury" to her and her family, she claimed.
