Although her character Jane Foster doesn't appear in "Thor: Ragnarok," Oscar winner Natalie Portman appears open to returning to the Marvel Cinematic Universe.

In a wide-ranging video interview with Deadline's Pete Hammond, the actress discussed her starring role in the biographical drama "Jackie," as well as her work in more mainstream blockbusters like "Star Wars" and "Thor." Addressing the challenges of performing against a blue screen, Portman said, "When you are doing those blue screen movies, you have to imagine everything outside and within. You have to create the whole world. It is like being a kid again."

Asked whether she might return to the Marvel Universe, Portman laughed and said, "Hopefully, one day, I'll figure it out."

Portman, who earned an Academy Award for her performance in 2010's "Black Swan," originated the role of scientist Jane Foster in 2011's "Thor." She returned for the 2013 sequel "Thor: The Dark World," but reportedly was "deeply upset" with Marvel Studios over the dismissal of director Patty Jenkins (who of course went on to helm Warner Bros.' "Wonder Woman").

Jane Foster doesn't return in the upcoming "Thor: Ragnarok," as Marvel Studios President Kevin Feige explained only a few scenes are set on Earth.

In August, Portman said that, as far as she knows, she's "done" with the Marvel Cinematic Universe. "I don’t know if maybe one day they’ll ask for an ‘Avengers 7’ or something," she said. "As far as I know I’m done, but it was a great thing to be a part of.”

Directed by Taika Waititi, “Thor: Ragnarok” stars Chris Hemsworth, Tom Hiddleston, Mark Ruffalo Idris Elba, Cate Blanchett, Tessa Thompson, Jeff Goldblum, Karl Urban and Anthony Hopkins. The film opens Nov. 3, 2017.
