Captain Marvel is about to solve one one of the biggest mysteries in the Marvel Cinematic Universe. According to Samuel L. Jackson, the film will reveal how Nick Fury lost his eye, leading him to sporting his trademark eyepatch in all his MCU appearances.

In a new interview, Jackson revealed the upcoming MCU blockbuster will show Fury losing his eye and expand his backstory, including the revelation that the future Director of S.H.I.E.L.D. once had a family.

"You'll see, specifically, the origin of what happened to his eye. You'll find out that he does have a family," Jackson told EntertainmentTonight. "You don't see them, but they are referenced in another way. There are things we talk about in his backstory that haven't been talked about before -- where he's from, what he's done."

In 2014's Captain America: The Winter Soldier, Fury hinted to Steve Rogers that the last time he trusted someone completely, it cost him his eye. Whether this claim was another lie by the super-spy has yet to be seen, but Jackson's comments imply he won't walk away from the film in one piece.

"We talk about him being in the war, leaving the war, being a spy and some of the things he did when he was a spy that got him to this particular place," Jackson added. "We get more of a backstory, and we get more of what turns him into this person that you originally meet in Iron Man."
