New career prospects 2007

In 2007, following the failure of two of her commercial releases, Zinta began working with art film directors, and turned towards neo-realistic movies, known in India as parallel cinema. She acted in her first English film, Rituparno Ghosh's The Last Lear, as a struggling theatre actress opposite Amitabh Bachchan. The film premiered at the 2007 Toronto International Film Festival, and was received well. The first reviews were approving, with one critic writing "It's great to see her doing a completely natural role. She played her role with real dignity and it was a pleasure seeing her getting back to her initial style of acting. Zinta said about her first art film, "I did think with art films that they don't pay you, they don't feed you, but I was wrong, and I'm so happy to be here.
Zinta next starred in Samir Karnik's Heroes (2008), a road movie about two final-year film students who, as a part of their assignment, travel a thousand miles across North India to deliver three un-posted letters written by army personnel who lost their lives during the 1999 Kargil war to their families. The story unfolds the journey of these students in three chapters and follows how they meet and are inspired by the families of the soldiers. Zinta is featured in the first chapter as Salman Khan's war widow, Kuljeet Kaur, a woman who becomes the sole breadwinner of the family and single-handedly raises her son. In preparation for the role, Zinta attended Anupam Kher's acting school to learn the dialect and mannerisms of a Punjabi woman. Both her performance and the film received rave reviews; Anand Singh of Hindustan Times wrote, "Karnik is merely interested in wringing tears the old-fashioned way, and not in starting a debate. He succeeds—mainly because Preity Zinta brings to a role a gravitas and dignity that is seen on the faces of ordinary women—this may be her coming of age as an actress.
By April 2008, Zinta completed shooting for Jahnu Barua's drama Har Pall and Deepa Mehta's Canadian film Heaven on Earth, a Punjabi language drama based on the true story of a non-resident Indian battered wife. Her performance in Heaven on Earth earned her the Best Actress (Silver Hugo) award at the 2008 Chicago International Film Festival, for "her strong yet subtle performance as a woman struggling to keep her dreams despite brutal realities
