Sony is expanding their Spider-Man cinematic universe to include a feature film centered on Spider-Man antagonists / allies Silver Sable and Black Cat, reports THR.

Chris Yost (X-23:Innocence Lost, X-Men), who helped script Thor: The Dark World and Thor: Ragnarok, is writing the script, which builds on a previous version from Westworld co-creator Lisa Joy. Matt Tolmach and Amy Pascal will produce the film.

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”).
