Halla Bol (English: Attack) is a Bollywood film released on January 11, 2008, and directed by Rajkumar Santoshi, who earlier directed The Legend of Bhagat Singh (2002) and Khakee (2004). The film stars Ajay Devgan and Vidya Balan in pivotal roles and 11 celebrities as themselves in guest appearances. Produced by Samee Siddiqui, the film's score and soundtrack is composed by Sukhwinder Singh, whilst Nataraja Subramanian and Steven Bernard are the cinematographer and editor respectively.

The film has touched many issues that have come in public eye in India lately, like the Jessica Lall murder case, Aamir Khan's involvement with the Narmada Bachao Andolan, Right to Information Act and public participation in fighting corruption, and 'Jan Natya Manch', whose leader theatre activist, Safdar Hashmi was killed at the hands of political goons while performing a street play by the same name, Halla Bol! in 1989.

Ashfaque (Ajay Devgan) is a small town boy aspiring to be a film star in the Hindi film industry. He joins a street theatre group run by a reformed dacoit Sidhu (Pankaj Kapur) who uses street theatre as a medium to bring about an awakening in the masses. Ashfaque struggles to give a creative vent to the actor in him in order to realize his dreams. Ashfaque's determined struggle pays off and he gets a break in films. He gets a new screen name - Sameer Khan. With the passage of time, the roles start becoming better and he moves up the success ladder in a very short time. Soon, he becomes Sameer Khan the superstar - one who can enact any role with finesse, get under the skin of any and every character with ease and walk away with audience applause. Sadly, amidst all adulation and applause, he slowly loses his own identity. He forgets his real self and imbibes all characteristics of the various roles essayed by him on screen. Corruption takes over his entire system, alienating him from all loved ones, including his wife Sneha (Vidya Balan). A shocking incident at a party changes everything, rocking Sameer Khan's lifestyle. He gets caught between his human self on one side and his corrupted superstar image on the other. Whether the conflict within him gives way to good sense and whether he is able to discard his corrupted image and emerge as a true life hero, becomes an integral part of this true life cinema.
