In 2008, Bobby starred opposite Priyanka Chopra, Danny Denzongpa and Irrfan Khan in the crime drama "Chamku", playing the lead character and titlesake of Chamku, a man raised by Baba (Danny Denzongpa), a Naxal leader based in the southern interiors of Bihar, after his family was brutally murdered.

Kabeer Kaushik, the director of the film had originally approached Bobby to play the lead role in his debut film, "Sehar", but despite liking the script, Bobby turned it down because at the time he was not prepared to work with a debutant director. Bobby next featured in "Heroes" as an army officer and Dhananjay "DJ" Shergill alongside a strong cast which included Salman Khan, Preity Zinta, Sunny Deol and Mithun Chakraborty. Although initially set to be released on 6 June 2008, it was pushed to 24 October 2008, the opening weekend of the holiday Diwali. Much of the filming took place in northern India, including Ladakh (notably Pangong Tso), Chandigarh, Punjab, and Delhi. Bobby's last role in 2008 was in the film "Dostana", as Abhimanyu Singh, supporting role to the films' main stars Abhishek Bachchan, John Abraham and Priyanka Chopra under the Dharma Productions banner. The film explores the story of two men who pretend to be gay but both fall in love with the same girl, their roommate. "Dostana" is the first Bollywood film to be filmed entirely in Miami, United States and went on to become the eighth highest grossing film at the Indian Box Office in 2008.
