As one of the longest serving true members of the MCU, Samuel L. Jackson will continue his run as Nick Fury in the upcoming Secret Invasion Disney+ series, as well as being rumored to appear in Captain Marvel movie The Marvels early next year. Having first appeared in the post credit scene of Iron Man to recruit Tony Stark to his “Avengers Initiative”, Jackson has gone on to appear frequently throughout the Marvel Cinematic Universe, sometimes in central roles and others, like in Avengers: Endgame, as a small cameo role that just reminds everyone that he is still very much part of that world.
