Tessa Thompson, who can currently be seen as Valkyrie in the Marvel Cinematic Universe film 'Thor: Ragnarok,' has implied that she might want to play another major comic book role. A fan tweeted at Thompson to tell her that she would make a great Alana from the comic series 'Saga.' Thompson said that was “obsessed” with Saga and tweeted out the cover to Saga #8. There have been no rumors of a 'Saga' adaptation is in the works. Co-creator Brian K.
