Based on Samuel L. Jackson‘s stories, Marvel really is one of the most secure organizations on the planet.

The Secret Invasion actor has been involved with the Marvel Cinematic Universe for years now, playing the iconic character Nick Fury.

During a recent interview, he opened up about some of the organization’s security measures to protect secrets about forthcoming movies and shows. He also revealed how Marvel responded when one of his scripts was stolen and put up for sale.

Speaking with Entertainment Weekly, Samuel said that Marvel has shot down drones that flew over set.

“And they followed one back to where the dude was. They found him and, yeah, they got him,” he continued. While that sounds extreme, he added that there were “worse examples.”

“I remember when we got ready to do Avengers, someone printed out a copy of my Avengers script that had my watermark on it, and put it online for sale. I was shooting in Canada and Marvel came to Canada,” he explained. “It had been printed in the production office… They found out who it was, dude quit, left the country. They set up a fake buy for the script, dude didn’t show up. It was crazy.”

If you watched the first episode of Secret Invasion, you might have noticed that Nick Fury is looking a little different. Samuel explained why.
