No matter what Ormax says, most of the actresses who debuted between 2010-2019 failed to make a mark at the box office and have no box-office pull, except Alia. Even Shraddha's Haseena Parker failed to even grab a decent initial. Most of the movies which have worked are due to other factors.
Even Disha Patani and Taapsee Pannu, who have somewhat carved their own niche, have limited appeal. I don't think they have that box-office pull yet ( though they are developing some sort of audience, but it's not full-fledged mainstream audience love). Kiara and Kriti are also a little popular, but not enough to have that craze.
In top 5, we have 3 actresses from 2000-2010 decade and Priyanka would still be there if she hadn't migrated to the West.
So I see no competition for Alia which these actresses could pose, and she continues her solo run at the box-office. Let's look at a few of her contemporaries who seem to be on the verge of stardom, but never cross the threshold:
1. Kriti Sanon
2. Kiara Advani
3. Yami Gautam
4. Ileana D' Cruz
5. Taapsee Pannu
6. Vaani Kapoor
7. Bhumi Pednekar
8. Disha Patani
These actresses are all much more beautiful than Alia, but seems like they are still struggling or are B-list actresses. Some of them like Vaani barely got a few films in her kitty.
Now the next generation of actresses: Jhanvi, Ananya, and Sara can never compete with Alia because even she is better than them.
Tripti and Sanya are good, but will they be able to oust Alia? I doubt it.
I think Alia will continue to maintain her numeo uno position at the box office, because all the good directors are signing her. I am being realistic I don't think she is going anywehrre.
