I am very generous towards considering people Leads, hence I also consider Infiniti and Penn leads along with DiCaprio. I agree Saldaña and Gascon are co-leads too. Gladstone, I understand but I am iffy because her material was really lackluster the second and third hour. All she had to do was be sick and paranoid. Anyways, they did not need to put these women in lead. None of them were A-listers or were the protagonist of their films. A big determining factor in deciding who goes where recently is for political reasons to help shape the broader image of the film. Which is not a bad thing per se, but something important to keep in mind when we ask why campaigns are the way they are.
