Diminutive but definitive, Aamir Khan brings to the Bollywood screen a will to experiment and a desire to be perfect. After making his debut in 'Qayamat Se Qayamat Tak' (1988), Khan went on to act in a dozen commercial duds before discovering the perfectionist in himself. Post 'Ghulam' (1997) it has been a different Aamir on play. He defied all conventional norms as a producer and decided to make Ashutosh Gowariker's 'Lagaan', a mock period film with a message.
