In 1999, Khan launched a production company, Aamir Khan Productions, whose first release Lagaan (2001) was nominated for the Academy Award for Best Foreign Language Film, and earned him the National Film Award for Best Popular Film. Also in 2001, he starred alongside Saif Ali Khan and Akshaye Khanna in the acclaimed drama Dil Chahta Hai. Lagaan and Dil Chahta Hai are cited in the media as defining films of Hindi cinema. After a four-year absence from film, Khan portrayed the eponymous lead in Mangal Pandey: The Rising (2005), a period film that underperformed at the box office, after which he played leading roles in two top-grossing films of 2006—Fanaa and Rang De Basanti.
Khan made his directorial debut with Taare Zameen Par in 2007, a drama on dyslexia starring Darsheel Safary, in which Khan also played a supporting role. The film proved to be a critical and commercial success, winning him the National Film Award for Best Film on Family Welfare. Khan played a man suffering from anterograde amnesia in the 2008 thriller Ghajini, after which he portrayed an engineering student in the comedy-drama 3 Idiots (2009), and a reclusive artist in the drama Dhobi Ghat (2010), which he also produced. He co-starred alongside Abhishek Bachchan and Uday Chopra as the antagonist of the adventure film Dhoom 3 in 2013, following which he played an alien in the over ₹7 billion (US$100 million)-grossing satire PK. Four of Khan's films—Ghajini, 3 Idiots, Dhoom 3, and PK— have held records for being the highest-grossing Bollywood film of all time.
