It really depends on your definition of a spoiler. Plus it’s in magazines and stuff? But still, if you want to be 100% surprised, maybe you shouldn’t
Just going to spoil it for everyone. Jimmy Olsen is Jenny Olsen and no one should care. Seriously, this movie is not going to have Superman’s Pal grow so huge she needs to be removed from the Earth. It is not going to have her temporarily be a Nazi. She is not going to ruin a Superman video game by making you play as Mon-El and save the planet from hypnosis. So it’s barely Olsen we’re talking about here, male or female. It’s someone with a camera who will at some point say “It’s Superman!” So shut yer pie-holes.
