It seems that Marvel Studios was not always as secure as the S.H.I.E.L.D HQ it portrays on film.

In an interview with Entertainment Weekly, Samuel L. Jackson recalled the time his watermarked Avengers script was stolen and put online for sale.

“It had been printed in the production office… They found out who it was, dude quit, left the country,” Jackson told EW.

This insider hijinx played out while Jackson was filming the movie in Canada, prompting Marvel executives to fly up and get to the bottom of it.

“They set up a fake buy for the script, dude didn’t show up,” Jackson shared. “It was crazy.”

This breach of security led to the implementation of stricter protocols, including shooting down drones flying over their filming locations to get a sneak peek of production.

“They shot one down,” Jackson told EW. “And they followed one back to where the dude was. They found him and, yeah, they got him.”

Jackson was interviewed alongside his new Marvel series Secret Invasion co-stars. Emilia Clarke, who plays G’iah, shared her experiences pertaining to taking security measures while filming Game of Thrones, which were influenced by Marvel, per Variety.

“When we were doing ‘Game of Thrones,’ when it started to get to the later seasons, some massive security changes happened,” Clarke spilled.

While talking with GOT showrunners David Benioff and Dan Weiss, she learned that at the core of these developments was Marvel.

‘”We’re just learning from Marvel. Whatever Marvel’s doing, we just want to do that,’” they had told her. “So that became, you don’t print anything — and then there was like me and Peter Dinklage being like, ‘I need it on paper! I can’t learn my lines without it being on paper!'”
