The expansion of Sony's "Spider-Man"-centric universe may take longer than originally planned. The studio has pulled "Silver and Black" from its release date of Feb. 8, 2019.

"Silver and Black" focuses on the characters Silver Sable, a mercenary who hunts war criminals, and Black Cat, an acrobatic burglar. The movie is to be directed by Gina Prince-Bythewood ("Beyond the Lights," "Love and Basketball"), but no casting announcements have been made — a sure sign the project was not close to making that February date. Sony is looking for another date.

In press for the Freeform Marvel series "Cloak and Dagger," Prince-Bythewood hinted that the movie still needs work.

"The update is just really pounding out the script," she said. "It all starts with the script. You gotta have a great script so we want to make sure that's right before we jump in."

"Silver and Black" was one of a number of projects Sony was developing within the Spidey-verse. The first of these is "Venom," starring Tom Hardy, which opens October 5.
