Brie Larson says 'Captain Marvel' is the ''bridge'' between Earth and space.

The Oscar-winning actress is set to star as Carol Danvers and her titular alter-ego in the 2019 standalone movie, and has said the character acts as the missing link between Earth and what's happening in the wider Marvel Comics universe.

Asked by Yahoo! Movies how the superhero fits in to the stories already established by the likes of 'Iron Man', 'Captain America', and 'Guardians of the Galaxy', Brie said: ''Well, quite simply, she's kind of like the bridge between these two worlds. She's the bridge between what's happening up in space and what's happening down on Earth.''

Meanwhile, Marvel studio head Kevin Feige previously admitted Brie, 27, had to overcome some tough obstacles before she was offered the role.

He said: ''Listen, we set the bar very high with the first casting decision we ever made with Robert Downey Jr. as Tony Stark. Since then, every single choice we've made, we have asked, 'Could it meet that bar?' Because that is what people expect of us, and that is what ... it's a very high bar.''

''Carol Danvers needs to be as rich and textured and real as the best of our characters. Maybe even more so. And we got very lucky that Brie - who has all of those attributes, and an Academy Award now - was still very interested in signing up and joining us to bring this character to life.''

The news of Brie's casting was first announced at San Diego Comic Con in July last year when the blonde beauty tweeted a picture of herself wearing a Marvel Studios hat and wrote: ''Call me Captain Marvel.''

She later added: ''Thanks for the love! I'm so excited to be part of the team.''
