Trivia, insights & behind the scenes
This Tamil original was so successful that Aamir Khan personally acquired remake rights, leading to the 2008 Bollywood version that introduced the 'Ghajini cut' hairstyle trend across India.
The fifteen-minute memory window was scientifically exaggerated—actual anterograde amnesia patients typically retain 30 seconds to a few minutes, making Sanjay's condition a narrative convenience that lets him form complex revenge plans.
