"LARSON INDUSTRIES R&D DEPT.," an in-costume Larson captioned a pic of herself reading up on her character.

The Room star has had no shortage of fun since her big casting announcement at Comic-Con last month, where she was introduced as the star of Marvel Studios' first female-led film. The actress has since posted a series of Marvel-filled pics to her Instagram.

It all started with the amazing declaration, "Call me Captain Marvel," the caption of a snap of herself posing in a Marvel Studios cap.

Then came a completely badass shot of Larson with the fellow ladies of Marvel.

"GIRL POWER – MARVEL EDITION," the Room star captioned a pic of the blockbuster lineup.
