Beyond that between 2002-05, he was largely out of work, and lived in a flat he shared with four other people, and survived by conducting occasional acting workshops. His appearance in Anurag Kashyap's Black Friday (2007) paved way for other powerful roles. His first lead role in a feature film was in Prashant Bhargava's PATANG, which premiered at the Berlin Film Festival, for which Nawazuddin's performance has been praised by world renown film critic Roger Ebert (awarding the film 4 stars), a role which 'transformed his acting style'. In 2009, he appeared in a cameo role in hit song "emotional attyachar" in the movie Dev D in his moniker as Rangila along with his duo Rasila (known together as Patna ke Presley). However it was his role of a journalist in Aamir Khan Productions's Peepli Live (2010), that first got him recognition as an actor. This was followed by a role as police informer Gopi in biopic, Paan Singh Tomardirected by Tigmanshu dhulia also in the same year.
He however became a household name post Kahaani (2012), where he played the archetypal short tempered cop Khan. Gangs of Wasseypur followed which furthered his fame.

Nawazuddin also played the lead role in the upcoming films, Gangs of Wasseypur - Part II and Aatma. He will be appearing in Aamir Khan's 2012 release, Talash. Gangs of Wasseypur is being touted as the career defining film for Nawazuddin where he played the role of Faizal Khan, as the second son of Sardar Khan, played by Manoj Bajpai. His gaudy style of dress, magnificent accent and out-of-the-way mannerism in Gangs of Wasseypur has left an impression on Bollywood critics. His film PATANG currently in release in the U.S. and Canada, is garnering much attention for Nawazuddin with rave reviews from the New York Times, Los Angeles Times and Roger Ebert.
