In its fourth weekend in theaters, Avengers: Endgame will actually have a post-credit scene in the form of a Spider-Man: Far From Home trailer.
Some have looked at Spider-Man: Far From Home as being its own sort of Avengers: Endgame post-credit scene, as it directly ties into that movie, and shows the aftermath of a world without Tony Stark.
Far From Home is rumored to include an actual post-credit scene though, and it allegedly spells out big trouble for Spider-Man’s future as a superhero.
Many believed that it would either tie-directly into Spider-Man: Far From Home or help set up Marvel Phase 4.
