Silver & Black is intended to be the 2nd film in Sony's Marvel Universe, a release date, casting, and its plot has yet to be uncovered.
This spin-off film will be centered around popular Spider-Man supporting characters Silver Sable and Black Cat.
Originally this film, along with Venom was intended to be in its own continuity and to not be connected to Spider-Man and the Marvel Cinematic Universe whatsoever, but as of July 2017, Amy Pascal stated that Silver & Black and Venom would be apart of the MCU and that Tom Holland's Spider-Man can appear in these films.
It is rumored that Kraven the Hunter and The Tarantula will be the main antagonists of the film.
It is also rumored that Mac Gargan/The Scorpion (Michael Mando) a character from Spider-Man: Homecoming would appear in the film, but this has yet-to-be confirmed, if he does appear it will mean that Silver & Black will officially be apart of the Marvel Cinematic Universe.
