For his role in Jaane Tu... Ya Jaane Na Imran won the Filmfare Best Male Debut Award.
Imran's next release Kidnap (2008), that also starred Sanjay Dutt and Minissha Lamba failed to generate much interest at the box office.
Imran Khan plays the role of a kidnapper in the film who abducts Minissha Lamba to settle an old score with Sanjay Dutt, who plays Minissha's father in the film.
Even his next release Luck in 2009 failed to bring any luck for Imran.
Directed by Soham Shah, the film had an ensemble cast that included Mithun Chakraborty, Sanjay Dutt, Shruti Haasan, Danny Denzongpa and Ravi Kishan.
Imran's next film I Hate Luv Storys (2010) fared better than his last two releases.
Paired opposite Sonam Kapoor, Imran played the role of a boy who doesn't believe in the concept of romance. But, as it happens in such films, he ultimately falls head over heels in love.
Imran's third 2010 release was Kunal Kohli's Break Ke Baad.
Deepika Padukone played Imran's love interest in the film and the two played childhood friends. The film did average business.
Imran got engaged to Avantika Malik, his long-time girlfriend on January 16, 2010 and the couple got married on January 10, 2011.
Delhi Belly is Imran Khan's six release as a lead actor and also perhaps his most awaited.
Directed by Abhinay Deo, the movie has Aamir Khan as one of the producers. The film has generated a lot of interest due to its explicit lyrics and also because of Aamir Khan's item number.
Delhi Belly also stars Vir Das, Poorna Jagannathan, Kunaal Roy Kapur and Shenaz Treasurywala.
Imran's forthcoming releases include Ali Abbas Zafar's Mere Brother Ki Dulhan opposite Katrina Kaif and a film with Kareena Kapoor tentatively titled Short Term Shaadi.
Born on January 13, 1983, Imran Khan made his first appearance on the big screen as a five-year-old playing the role of a young Aamir Khan in the 1988 superhit Qayamat Se Qayamat Tak.
With Aamir Khan and producer-director Mansoor Khan as uncles, Imran appeared again as a kid Aamir Khan in Jo Jeeta Wohi Sikander (1992).
Imran made his debut as a lead actor in Abbas Tyrewala's 2008 film Jaane Tu... Ya Jaane Na opposite Genelia D'Souza.
