Natalie Portman could make a surprise appearance in the fourth 'Avengers' movie.



The Academy Award-winning actress played the part of Jane Foster in the 'Thor' franchise, and director Anthony Russo has hinted at Natalie returning to the Marvel Cinematic Universe.



Asked whether the character of Jane was still alive, Anthony and his brother became coy and refused to commit to an answer because it might've given fans an insight into their plans.



He told HuffPost: "When we say spoiler, we mean potential spoiler."



Jane last appeared in a Marvel movie in 2013's 'Thor: The Dark World', but Natalie has previously admitted to being open to a return to the franchise.
