of the music industry, addressing the themes of envy, jealousy, insecurity, anxiety, manipulation and anger. The film, which featured Deol alongside Upen Patel, Kangana Ranaut and Celina Jaitly was generally praised by critics, especially for its choreography, and Deol received some positive reviews. Taran Adarsh of IndiaFM.com said after viewing the film, "Both Bobby and Upen get fabulous roles and the two actors make the most of it. Bobby is one of the most under-rated actors around.

This film was followed by brief special appearances as himself in Om Shanti Om and Nanhe Jaisalmer. In 2008, Deol starred opposite Priyanka Chopra, Danny Denzongpa and Irrfan Khan in the crime drama Chamku, playing the lead character and titlesake of Chamku, a
