Ghajini is a 2008 Indian action thriller film that is a remake of the 2005 Tamil film of the same name. The Tamil version, also directed by A.R. Murugadoss, was inspired by the 2000 American film Memento.
The Hindi remake of Ghajini features Aamir Khan, who plays a businessman suffering from anterograde amnesia, a condition that prevents him from forming new memories. The film follows his quest for revenge against the person who murdered his girlfriend.

Both films are known for their unique narrative structure, which flips back and forth between the present and the past, and for their intense action sequences.
While the Hindi remake of Ghajini follows the basic plot of the Tamil version, there are some key differences. For example, the Hindi version features a more prominent love story and a more elaborate climax.
Overall, Ghajini is a remake of the 2005 Tamil film of the same name, which itself was inspired by the 2000 American film Memento.
