Neither Silver Sable nor Black Cat have explicitly appeared in Sony’s previous iterations of Spider-Man, and the project is not considered a spinoff of Spider-Man Homecoming, which releases July 7 (see “First Official 'Spider-Man: Homecoming' Trailers”).Sony recently set a release date for Venom, another expansion in its Spider-Man universe, which is scheduled for December 18, 2018 (see “Date Set For 'Venom' Movie”).
