When last we saw Jane Foster in the Marvel Cinematic Universe, she and Thor were getting smoochy smoochy down on Earth. She was then away for work in Avengers: Age of Ultron, and now the character played by Natalie Portman may be gone for good. Talking on the Empire Podcast, Marvel Studios President Kevin Feige confirmed what we'd already heard — that Portman wouldn't be in the soon-to-film third Thor film, Thor: Ragnarok. There are "many reasons" for her absence, according to Feige, "Many of which are in the film so you will see that." He also said "There are only a couple of scenes on Earth in this movie; 80 to 90 per cent takes place in the cosmos," which is a reasonable explanation for why she doesn't fit in the story. (It would be weird for Jane Foster to be present but have to wear a space suit for most of the film.
However, while Portman's absence will be explained in the film, you have to wonder if there are other reasons for her absence. Portman is a massively popular, Oscar-winning actress, who kind of swore off franchise films after the Star Wars prequels. She appeared in Thor as well as Thor: The Dark World, but never seemed too excited about it off screen. It's not like she needs a big, hit movie to star in so giving her an exit in the script seems like the smart move.
Now, whether or not she'll make an appearance in Avengers: Infinity War, or will just be written out completely, remains to be seen. Either way, there's a good chance we've seen the last of brilliant scientist Jane Foster in the MCU.
As for her boyfriend, we'll see him, along with the Hulk, Loki, Sif and several other new characters played by the likes of Tessa Thompson and Cate Blanchett, in Thor: Ragnarok when it hits US theatres 3 November 2017.
