We all know that Marvel Studios takes their security seriously, but it turns out they’re even more thorough than any of us imagined. The studio is so guarded with their scripts that they’ve built an actual SCIF for their actors to read them.

If you’re not familiar with a SCIF, it stands for Sensitive Compartmented Information Facility. It’s a highly secured room where high ranking military officials or politicians can read classified material in a secured setting. You can’t bring your phone or any communication device to a SCIF, and you can’t enter without high security clearance.

The government uses SCIFs for things like nuclear secrets, so it’s crazy to think Marvel Studios is using that kind of security for their scripts. That’s how serious they are about guarding spoilers.

Elizabeth Olsen, who plays Wanda Maximoff in the MCU, says Marvel has used these highly secured rooms for movies like Endgame. “On Infinity War I just got my pages. I think I got a hard copy, which is nice,” Elizabeth Olsen reveales during a spotlight panel at C2E2 2026.

“They offer you, if you want, to read the whole thing to sit in an office with no windows and read it off an iPad that’s locked. So you have that option if you want to know what’s going on. But they were pretty good at letting us know what we needed. The truth is you don’t need to know everything to do your job. I’m okay with that. But Infinity War we just got our pages. Endgame, I don’t think I saw a single page of script, but I also, like, was hardly in that movie.”

Avengers: Secret Wars is anticipated begin filming later this year. This means that as you’re reading this, there might be a Marvel actor sitting in the Marvel Studios SCIF reading the script right now.
