Hi there, well, there are some films (not many) that are about aging couples (Saaransh) which have and older female lead, but they are VERY scarce. Recently Rekha at 60 will be the main protagonist of Super Nani.
The eldest female being awarded with a Filmfare for a leading role was Nutan when she was only 42.
The over 40/50 actors look plain ridiculous beside actresses in their 20s. As if they did not realize they are not doing any favours to themselves. The Khans, so influential, should be, in an ideal world, be the ones who would try to make a change by starring with heroines their age, but they are too busy chasing their youthful image to care.
I am also pulling for a film with an older heroine and a young guy (Madhuri/Ranbir would be my pick), but for that they need a serious justification - while nobody bats an eyelid or tries to justify the huge age differences between heroes and actresses their age. Well, that is sexism in action of course…..
