Early work (1997–99)

In 1997, Zinta met film-maker Shekhar Kapur when she accompanied a friend to an audition, and was asked if she would audition too. Upon seeing her audition, Kapur insisted that she become an actress. She was originally scheduled to make her screen debut in Kapur's Tara Rum Pum Pum opposite Hrithik Roshan, but the filming was cancelled. Kapur later recommended her for director Mani Ratnam's movie Dil Se. Zinta often recalls that when she joined the film industry, her friends teased her that she would typically "wear white saris and dance in the rain", thereby motivating her to play different parts.
Zinta commenced shooting for Kundan Shah's Kya Kehna, whose release was delayed until 2000.[17] The delay of another film, Soldier, meant that her first release was Dil Se (1998) opposite Shahrukh Khan and Manisha Koirala. She was introduced as Preeti Nair, a middle-class Delhi girl and Khan's fiancée. The film was considered an unusual launch for a newcomer, as her role called for only 20 minutes of screen time. However, she was eventually noticed for her role, particularly for the forthright character she played. Her scene with Khan, in which she asked him, "Are you a virgin?", became well-known, and her portrayal earned her a Filmfare Best Supporting Actress Award nomination. She played her first leading role in the action-drama Soldier (1998), a commercial hit of the year. She won the Filmfare Best Female Debut Award for her performance in both Dil Se and Soldier.
Zinta next acted in two Telugu films, Premante Idera (1998), opposite Venkatesh; and Raja Kumarudu (1999), opposite Mahesh Babu. She followed with the leading role in the thriller Sangharsh, alongside Akshay Kumar. The film, based on The Silence of the Lambs (1991),was directed by Tanuja Chandra and written by Mahesh Bhatt. Zinta portrayed the character of Reet Oberoi, a CBI officer who falls in love with a captured killer played by Kumar. The film was not a box-office success, although Zinta's performance was appreciated by critics
