The film, which marks Farah Khan's directorial debut, stars Shah Rukh Khan, Sushmita Sen, Suniel Shetty, Amrita Rao and Zayed Khan, alongside Kirron Kher, Murali Sharma, Kabir Bedi, Boman Irani, and Naseeruddin Shah. In the film, Major Ram Prasad Sharma is sent on a covert mission to pose as a college student and protect the general's daughter from a dangerous rogue soldier and reunite with his father’s long lost family.

Development for the film began as early as 2001; however, it faced a number of delays during production. Main Hoon Na is notable for approaching the Indo-Pakistani conflict from a neutral perspective. Filming took place at St. Paul's School and the surrounding state of West Bengal. The film is also the first production of Red Chillies Entertainment.

Main Hoon Na was released on 30 April 2004 to positive reviews from critics and became a commercial success by grossing ₹84 crore, thus becoming the second highest-grossing Indian film of 2004, only surpassed by another Shah Rukh Khan-starrer Veer-Zaara.

At the 50th Filmfare Awards, Main Hoon Na received 12 nominations, including Best Film, Best Director (Farah), Best Actor (Shah Rukh), Best Supporting Actress (Rao), Best Supporting Actor (Zayed) and Best Villain (Shetty), winning Best Music Director (Anu Malik). A snippet of "Lament" from Light of Aiden (Celtic Version) is used throughout the film.
