'Stranger Things' was renewed for a fourth season last September.
'Stranger Things' Millie Bobby Brown almost left acting after she couldn't get hold of a role in Game of Thrones.
The actor confessed the news on an episode of "The Tonight Show Starring Jimmy Fallon, " reported by Variety.
The actor became "very disheartened" by the Hollywood and television industry, which she accused is "just full of rejection 24/7."
"I feel like you do get a lot of noes before you get a yes," she explained of the casting process, adding that she was auditioning for "anything really" at the time.
The star- who currently stars in the Netflix film Enola Holmes — said she auditioned for Game of Thrones, which was a role she "really wanted."
"I got a no for that and then that's when I was like, 'Oh, this is really difficult,'" she told Fallon.
After nearly quitting her career as an actress, Brown said she had her "last kind of go" at a "Netflix show called Montauk," which later became Stranger Things.
"I auditioned and two months later they got back to us and said, 'Hey we'd love to Skype with you' and I Skyped with them, and the rest is history," she said with a smile.
"Montauk was definitely the one that kind of gave me that hope of doing it all again," Brown added.
