Actress Preeti looks fit, bubbly, prim & young here, keeping aside what her real age may be.
Proper makeup, style, costumes, hair, body language etc. can make even 20's age actor or actress look like some matured 40's even elderly 60's/70's onscreen, its also about convincing styling, presentation, characterization & usage. There are many films/web series/TV serials as examples that did convincingly.
As I lamented, entire Neerja's sub track in KA isn't emotionally connecting, as it was supposed to be. 😳Crew could have invested more efforts in brainstorming how writing, styling & execution can be made better convincing before shifting focus to Neerja rather than copying OG track of senior citizen donor, mostly as is in KA. Also then would have gone for some appropriate casting for Neerja & her son's roles.
How about this as Neerja backstory for example? Neerja could have been shown as some rich widow who lost her husband & sons in some grave accident,😒 where as her own brother or BIL were harassing her to loot her wealth, as she has no heir left. But she has some unfulfilled dream of her family where she wants to spend her wealth. Frustrated with relatives she left home, came down to Mumbai from another city, was working with some NGO living in their quarters. As her relatives came hunting for her to NGO office, after being bone marrow donor to Aarav she was searching for new guest house to live in Mumbai, where her relatives can't track her easily. In Katha's house she felt both secure & loved.
Similarly there could be many other ways to showcase lonely sad status of Neerja in current KA version also in a steady manner.
@bold very interesting idea indeed.
