Lagaa Chunari Mein Daag is inspired by Tamil movie Aval Oru Thodarkathai which is, in turn, remade as Aaina (1977), by K Balachander. The film starred Mumtaz, Rajesh Khanna, A K Hangal and Nirupa Roy.
The story goes like this: Mumtaz's father, a Brahmin priest, has a large family to support. One of his children (played by Mumtaz) falls in love with Rajesh Khanna, who belongs to a lower caste. Denied Mumtaz's hand in marriage, Khanna then joins the army where he dies.
Tired of poverty, Mumtaz's mother tries to poison her children but stops when Mumtaz intervenes. Mumtaz then goes to the city to earn a living. Once there, she finds it difficult to secure a decent job and resorts to prostitution.
Lagaa Chunari Mein Daag, starring Rani Mukerji, Konkana Sen Sharma and Abhishek Bachchan, shows Rani and her sister (Konkana) trying their best to survive in Benaras. Rani then undertakes a journey, which ends in prostitution, to ensure that her sister gets a decent education.
The only difference here, is that Rani's lover is alive.
