Nathan Edmondson, the current writer of Black Widow's ongoing comic series, has expressed support for a Twitter campaign that pushes for a solo movie for Scarlett Johannson's Black Widow. As part of his support for the effort, he wrote up some script pages for a Black Widow movie.
The six pages of script that Edmondson uploaded depict an action sequence for Black Widow in what appears to be a teaser, ending with the Black Widow logo.
