Obviously none of these people are real movie stars of yesteryear but they definitely could've utilized a younger star that actually got some buzz going w/ Gen Z & millennials. Maybe they still wouldn't have turned out in large numbers cause the reviews were meh but large swaths of the internet clearly take note of what actors like Tom Holland, Anya Taylor Joy, Florence Pugh, Zendaya, etc do. A lot of their red carpet appearances and interviews go viral. PWB does not have that kind of appeal right now cause she didn't really take advantage of her Fleabag fame well imo.
I mean look at Margot on the Barbie press tour! Every single outfit she's worn gets her trending in the 10s of thousands.
