After 10 years of doing superhero movies, I guess it is just a matter of time before Marvel started focusing on their villains. According to The Hashtag Show, Marvel has finished a script for their IP called Dark Avengers.
Created by Brian Michael Bendis, and first introduced in Dark Avengers #1 in 2009. The Dark Avengers is a group of “heroes” lead by none other than Norman Osborn. Norman has gathered together a group of villains that is ordered to pretend to be the Avengers.
Granted, Marvel writes scripts for movies all the time, so who knows if this will be one that they will use or not, would the report be true. Plus this need to be another collaboration with Sony so they can use Norman.
