Spider-Man: Far From Home may confirm the theory that Nick Fury (Samuel L. Jackson) was also a Skrull in Avengers: Age of Ultron. It was announced a few years ago that the green shape-shifting alien race known as the Skrulls were coming to the Marvel Cinematic Universe. The news immediately sent Marvel Comics readers buzzing with the possibilities, and it also saw many begin to wonder if some characters the MCU has already introduced could be revealed to be Skrulls.

Out of everyone the MCU has to offer, one popular theory was that Nick Fury was actually a Skrull. This theory only grew in popularity when a younger version of the character was announced to be in Captain Marvel, which would also see the Skrulls debut. While a Skrull didn't replace the regular Fury in 1995, the solo movie did reveal that he is an ally to the entire race. However, the film's setting and the ending left viewers wondering if they were in contact at all after this encounter. Spider-Man: Far From Home reveals that they have been, and added more fuel to another MCU theory in the process.

In the post-credits scene of Spider-Man: Far From Home, Fury is shown driving in a car with Maria Hill (Cobie Smulders) as they begin to contact their boss. That is when the transformation came and revealed that both Maria and Fury were Skrulls for the entirety of the film's story. The real Nick Fury was out in space with other Skrulls - likely building the operating base for SWORD, which is the cosmic version of SHIELD. The reveal that Fury is still in contact with Talos (Ben Mendelsohn) and the Skrulls opens the door for this switch to have happened before, like in Avengers: Age of Ultron.

The theory that Fury is a Skrull in Avengers: Age of Ultron stems from one incredibly small detail that initially appeared to be inconsequential. When Fury visits the Avengers at the Barton household, he is shown making himself a sandwich and cutting it diagonally. The reason fans started to pick up on this detail is that Fury says in Captain Marvel that he will not eat toast that has been cut in this style. Fans believe that this preference for his bread extends beyond just toast and to sandwiches as well. So, did Fury simply lose this preference over time or is this a small detail that someone like Talos wouldn't know about Fury while impersonating him?

While the theory is still not confirmed to be accurate, Spider-Man: Far From Home playing with the idea that Fury has had a Skrull pose as him does make it more believable. Talos' version of Fury in the new film is not a perfect copy, though, as Fury's vocabulary is not the same. The Talos Fury slips up a few times in Spider-Man: Far From Home - calling Earth "your planet" and holding Captain Marvel's name in high standing. Since Age of Ultron takes place roughly eight years before this swap, it would stand to reason that Talos' portrayal is even less identical at that point. But, Fury seems to be his usual self in all of his scenes in the 2015 film, making a Talos impersonation not as believable - unless he's gotten worse over time.

At this point, the reveal in Spider-Man: Far From Home is not enough to confirm that a Skrull was also posing as Fury in Avengers: Age of Ultron. It's possible such a revelation could come in future MCU movies or that Kevin Feige will confirm it to be accurate down the road. But as of right now, this is still just a fun theory.
