Numan Acar, who is expected to play the Chameleon in the upcoming Spider-Man: Far from Home sequel, may have accidentally confirmed that Cobie Smulders, who plays Maria Hill in the MCU, will be involved in the sequel in some capacity.
Acar posted a selfie of himself with a number of hashtags that included #cobiesmulders. He has since removed the hashtags from the post, but no mention of why he had chosen to do so. Samuel L. Jackson has also recently taken to Instagram on July 11 with a suspicious S.H.I.E.L.D post: “Back to the familiar, the comfortable, the lovably fierce…” Jackson’s post said, likely referencing his role as Nick Fury.
At the end of Avengers: Infinity War we see both Hill and Fury fade into dust as they call on Captain Marvel. If the pair of characters are to return in Spider-Man: Far From Home after the events of the next Avengers movie, it can be assumed that S.H.I.E.L.D will have some impact in the next Spider-Man film, which could have significant implications for the cinematic universe.
The return of Nick Fury and Maria Hill would, at least in some part, signal the return of S.H.I.E.L.D. If S.H.I.E.L.D is to be rebuilt, it could mean that some of the original Avengers like Tony Stark, Steve Rogers, Bruce Banner, Natasha Romanoff, Clint Barton and others could possibly be stepping down from their superhero roles to help rebuild S.H.I.E.L.D from the ground up in order to support the next generation of heroes with Peter Parker at the forefront.
Kevin Feige has hinted everywhere that the next Avengers film will be the final chapter for many of the original characters, and that Spider-Man will be one of the most important characters in Phase 4 of the MCU. Feige has also made it known that the events of the next Avengers film will influence the plot of Far From Home significantly.
Only time will tell but we’ll keep our fingers crossed! (Source)
