As Marvel Studios president Kevin Feige previously revealed, Captain Marvel drops in on Fury’s life when he believes the best days of his life are over due to the Cold War having wrapped up.
He hasn’t had any experience with superheroes or aliens yet, but once he crosses paths with Carol Danvers, his life will be forever changed, marking his first step towards becoming the man responsible for bringing the Avengers together.
Of course, the other big takeaway from this Captain Marvel picture is that Nick Fury still has two working eyes at this stage of his life, though I suspect that will change by the end of the movie, and that cut above his right eye makes makes for some on-the-nose (on-the-eye?) foreshadowing.
