A lot of actors are just jumping on the bandwagon of superhero movies without actually knowing much about them. Some of them a little too late I might add.
The fact that they thought they were joining the MCU and she doesn't even know Tom Holland's Spider-Man movies says a lot. Is just a bigger paycheck for them and promises of franchise money. I don't blame them but, come on, put a little effort into what you're getting into. Just looking at Sony's previous outings should give you some kind of clue.
