Warning: Avengers: Endgame and MCU spoilers will be found below. Ever since 2008?s Iron Man (when fans first caught a glimpse of Samuel L. Jackson?s Nick Fury in a post-credits scene), every MCU movie has followed the tradition of giving a glimpse of what was to come next. So that was our goal and that was really why we had no tag because ? even the people at Marvel aren?t thinking about the future of Marvel.
