Apparently Nick Fury is going to have some serious makeup in the upcoming Marvel Studios film Captain Marvel. We can say that, because the man behind the character, Samuel L. Jackson, posted an image to his Instagram showing some of the BTS process.
Specifically, the actor, encased in green goo, fell asleep during the lifecast process:
This begs the question: why does Director Fury need a lifecast? It could be a simple explanation; maybe the existing casts to create the signature Fury scar and eye patch aren't available to the Captain Marvel makeup team. This would make sense, because it's been a while since we've seen Jackson in an MCU film. Also, there's the fact that this film is set in the '90s, so maybe his patch is different.
The reason I'm leaning towards is maybe, just maybe, we'll be getting the story behind Fury's ocular injury, and it'll be due to Skrulls. According to several formative comics, the injury was sustained by a grenade blast during WWII, but we're pretty sure that's not how Jackson's Fury was injured.
In the recent Avengers: Infinity War Entertainment Weekly issue, Marvel Studios boss Kevin Feige revealed that Captain Marvel is the first superhero that Nick Fury meets, and that we'll be seeing that moment in the upcoming film. He went on to say that Captain Marvel is done in the style of a '90s action film, something we haven't seen in the franchise yet.
Some fans have speculated that perhaps Fury is actually a Skrull himself, and that's why the full face cast was happening.
Only time will tell. Captain Marvel is currently filming, and has a release date of March 6th, 2019.
