These days, Marvel Studios does a pretty good job of keeping its biggest secrets under wraps. We still get the odd leak and they definitely need to do something about all those test screening reports, but for the most part, the MCU is a pretty tight ship.
During a recent interview with Entertainment Weekly, Secret Invasion star Samuel L. Jackson - who has been part of this franchise since 2008's Iron Man - discussed the level of secrecy surrounding his Marvel work.
That includes security shooting down drones which attempt to capture set footage from the studio's movies and TV shows!
"They shot one down," the legendary actor confirms. "And they followed one back to where the dude was. They found him and, yeah, they got him."
"There are worse examples than that," Jackson continued. "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. 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."
Had that script leaked, it would have been huge. At the time, The Avengers was Marvel Studios' first $1 billion blockbuster and the plot being revealed in advance would have spoiled everything from The Hulk's battle with Loki to Agent Coulson's death and even Thanos' mid-credits scene appearance.
We'd certainly be intrigued to learn what became of the thief who Jackson says left the country and can't help but wonder if those infamous Marvel snipers are more than just an easy way for actors to dodge spoilery questions!
The first episode of Secret Invasion is now streaming on Disney+.
