In 2004, she played the lead role of army wife Sandra Williams in Hum Kaun Hai?, a supernatural thriller. The film opened to a mixed critical reception, but Kapadia's performance received positive comments. Subhash K. Jha noted that she "carries the film beyond where it would have been otherwise"; Rama Sharma of The Tribune wrote of her performance, "Dimple lends all her charisma to help the script sail through dead ends. Whether she is scared or scolding children, she has a powerful presence." 2005 saw Kapadia and Rishi Kapoor reunite as a lead couple for the third time after Bobby (1973) and Saagar (1985) in Pyaar Mein Twist. They starred as two middle-aged single parents who fall in love and later have to deal with the reaction of their children. The film generated mostly negative reviews, with several critics concurring that the chemistry between the lead pair is what makes the film watchable. In a two-star review, Khalid Mohamed called Kapadia "a dream actress", but ultimately concluded, "See this twisteroo if you must, only for the undiminished Kapoor-Kapadia chemistry." Few people went to see the film; within two weeks it was declared a flop. In 2006, she co-starred with Saif Ali Khan and Naseeruddin Shah in the psychological drama Being Cyrus (2006), an English-language arthouse feature directed by Homi Adajania. Kapadia enacted the part of Katy, Shah's neurotic and unfaithful wife who runs an affair with Cyrus, a young man who enters their house as an assistant. Her work received varied comments. According to BBC's Poonam Joshi, "The descent into despair of Dimple Kapadia's Katy is enthralling." Derek Elley from Variety, however, panned her for "wildly overact[ing]", with similar sentiments being shared by several critics, including Shradha Sukumaran from Mid Day, who labelled her performance "over-the-top and jerky". In V. K. Prakash's Phir Kabhi Kapadia and Mithun Chakraborty played ageing people who meet at a school reunion and rekindle their high-school romance. At the request of her son-in-law Akshay Kumar, she voiced the character of Devi, the mother of the title character of an elephant (voiced by Kumar) in the animated movie Jumbo (2008).
