• The next MCU film is the next Spider-Man film, and we already know Tom Hardy's been cast as Eddie Brock, who becomes Venom, so I'm thinking/hoping the black costume shows up in Avengers 4 for Peter to bring back to Earth.
The Venom movie is a standalone Sony production. Its not connected to the MCU or even the Tom Holland Spidey movies.
