Variety is reporting that Angela Bassett is joining the current Green Lantern production as government operative Amanda Waller.
What's interesting about this development is that the character of Waller has been associated more with comic books like Suicide Squad and Checkmate instead of Green Lantern. She has also been portrayed in other shows like the Justice League cartoon and recent episodes of Smallville.
My suspicion is that Bassett's appearance may similar to Samuel L. Jackson's appearances in upcoming Marvel productions as super-spy Nick Fury. A reoccurring character that will make appearances in various movies as a means of tying all the different characters together.
With reports that Warner Brothers is planning on using movies based on DC superheroes as a replacement for the Harry Potter franchise, there will be plenty of opportunities for Waller to make more big-screen appearances.
