Natalie Portman gives one big spoiler alert about 'Thor: Love and Thunder'

Star Natalie Portman by mistake spills all about part of Thor: Love and Thunder in a recent chat. 

Portman has not been casted for the Marvel Cinematic Universe and this has begun to show. 

At a press conference for the upcoming movie, the Black Swan actor discussed one new dimension of her role,  "No, completely different. But I think he's obviously very assured and experienced in being a superhero, and she's just trying to figure it out." 

Further adding, “She's new at it. And also keeps reverting to human form, so there's kind of danger always that, like, it might be her last moment getting to experience that."

As she said this, the actor checked herself and continued, "I don't know that might be… that might be a big spoiler, sorry." 

In isolation, Natalie’s comment may sound innocuous but a look at her character’s comic book origins tells a lot about why she felt it was a spoiler.
