Sisters, Chanchal & Madhubala.
A genuine colour picutre from an old Filmfare
On the sets of Madhubala's own home production 'Naata' (1955) - A film about two sisters who are pretty much tied to the hip; the younger of the two (Chanchal) wanting to see the older sister (Madhubala) be happy in what she thinks is a potential marriage proposal for her older sis (a potential strapping fella who just recently moved to the village - intellectual, kind, caring, seems like he's fascinated by Madhu and taken by her beauty etc etc etc - seems too good to be true eh?) The younger sister encourages the emotions of the older. Well, turns out the dude is already married and brings back his new bride to the village to meet everyone; witnessing this, and wishing him a long life and happy marriage - through heartache, the older sister passes away in her younger sisters arms.
Quite scary and coincidental how the main character dies of heartfail/ache eh?
