Aamir's GHAJINI, Tamil GAJINI, English MEMENTO (2000) and PASAND APNI APNI (1983)

Last week I saw Pasand apni apni of basu da,, and 1st half of Ghajini was completely taken from it..of mistaken identity of a rich man..

pasand apni apni itself is copied from" happy go lovely" an old english movie.

Hope this link will help u.

I think gadar ek prem katha should be added in this list.
It is highly inspired from punjabi film shaheed e mohabbat boota singh starring gurdas mann.
Similarity is in title too gadar ek prem katha and shaheed e mohabat and in lead characters as tara singh and boota singh. Shaheed e mohabbat was directed may be by manoj punj who also directed national award winning film waris shah again with gurdas mann. Waris shah went on to win 4 national awards.
In the first half gadar looked ditto copy of shaeed e mohabbat. shaeed e mohabbat was released in late 90\'s featuring ustad nusrat fateh li kahn\'s song \'ishq da rutba\' and many other songs of gurdas mann. climax was changed in gadar. if you will see shaheed e mohabbat you will find it quite touching. not to forget divya dutta was cast opposite gurdas mann playing the role what amisha patel played in gadar. well i must say 90% of bollywood movies are copies of hollywood or regional films or previous hindi cinema.

plot of shaheed-e-mohabbat .
directed by shamim ara and manoj punj.

The film is set in 1947. The exodus has begun after Partition. A Sikh ex-military man in his thirties finds a 16-year-old Muslim girl alone in a nearby village and brings her home. But the villagers tell him he should either marry her or leave her in a camp where people bound for Pakistan are located. But he decides that since he\'s far older, he\'d better leave her at the camp. As he is about to send her off with a man bound for the camp and who is prepared to marry her there, she asks Buta Singh if he is so poor that he cannot even feed her two Rotis per day to keep her alive. Whereupon Buta Singh decides to marry her. They have a baby girl. And Buta is pretty happy that despite being overage, matrimonially speaking, he\'s leading a pleasant life. Others of his class usually had to actually buy women from Uttar Pradesh and Bihar whom they married. A jealous uncle who realizes the family property will now go to the Muslim girl, forcibly dumps Buta\'s wife into a truck bound for Pakistan. Buta realizes what has happened, sells all his land and goes along with his child to Pakistan illegally. He\'s quickly arrested and brought before a judge who\'s quite willing to free him if his wife owns up. But, under pressure from her family, the girl backs off. A disillusioned and distraught Buta jumps with his daughter before an oncoming train. He dies, but his daughter is saved. Pakistani youth, overcome by this, hail him thus: Shaheed-e-Mohabat (a martyr in the cause of love), erect a memorial and a trust in his name

i m happy for gadar\'s business but the credit should be given to the original film makers. or the producers bought rights?
