Aap Ki Khatir, co-starring Akshaye Khanna, Ameesha Patel and Dino Morea. Neither the film nor Chopra's performance were well received. Sukanya Verma of Rediff.com stated that Chopra's portrayal of Anu was "erratically sketched" and that her character was never consistent: "first flaky, then cool, and later, sensitive". Chopra's final release of 2006 was Farhan Akhtar's action-thriller Don (a remake of the 1978 film of the same name), with Shah Rukh Khan. Chopra portrayed Roma (played by Zeenat Aman in the original film), who joins the underworld to avenge Don for killing her brother. Chopra received martial-arts training for her role in the movie, and performed her own stunts. The film was declared a box-office success in India and overseas, with revenues of . Raja Sen of Rediff.com found Chopra to be film's "big surprise"; he believed that Chopra convincingly portrayed Roma, "looking every bit the competent woman of action" and wrote "This is an actress willing to push herself, and has definite potential for screen magic. Not to mention a great smile." Setbacks and resurgence (2007–2008) In 2007, Chopra had two leading roles. Her first film was Nikhil Advani's Salaam-e-Ishq: A Tribute to Love, a romantic comedy-drama in six chapters with an ensemble cast. She was featured opposite Salman Khan in the first chapter as Kamini, an item girl and aspiring actress who tries to land the lead role in a Karan Johar film with a publicity gimmick. Film critic Sukanya Verma praised her flair for comedy, especially her impressions of Meena Kumari, Nargis and Madhubala. Both Salaam-e-Ishq: A Tribute to Love and her next film, Big Brother, proved unsuccessful at the domestic box office. In 2008, Chopra starred opposite Harman Baweja in his father's Love Story 2050. Chopra played a double role, so she colored her hair twice; once red to portray the girl from the future and then black for the girl of the past. Her performance was poorly received; Rajeev Masand was unimpressed with Chopra's chemistry with her co-star, remarking that her character "fails to inspire either affection or sympathy". She next appeared in the comedy God Tussi Great Ho, portraying a TV anchor opposite Salman Khan, Sohail Khan and Amitabh Bachchan. Chopra next starred as a kindergarten teacher in Chamku opposite Bobby Deol and Irrfan Khan, and played the role of Sonia in Goldie Behl's fantasy superhero film Drona opposite Abhishek Bachchan and Jaya Bachchan.
