Two hour-long superhero film franchises like those in the MCU seem to never have time to address subplots. In the upcoming "Thor: Ragnarok," there will be some explanation as to what happened between Thor and his Earth-based girlfriend, Jane Foster, played by Natalie Portman. In the first two "Thor" films, the pair struggled to make the relationship work after Jane met and fell in love with Thor over a long weekend in New Mexico. In "Thor: The Dark World," she played the girl who never got a call back, despite her otherwordly boyfriend being a timezone away in New York, fighting aliens.

In the upcoming "Thor: Ragnarok," Chris Hemsworth promised that a resolution will finally be reached with the subplot of Jane and Thor's romance.

Natalie Portman doesn't have further MCU commitments

In August, Natalie Portman told the Wall Street Journal that she's not currently booked for any further MCU films, meaning that she's out of the upcoming "Thor: Ragnarok." It makes sense given that the Taika Waititi-helmed film is not set on Earth, where Jane lives. But fans need not worry as Chris Hemsworth told Screen Rant that while "There was a whole different affection and love there," Waititi has decided to have "some very respectable fun with how that relationship may have come to an end."

Thor moving on with Valkyrie?

Now that Thor and Jane Foster may have ended their relationship, the God of Thunder may have another lady in his sights.

This time, it's Tessa Thompson's Valkyrie, which Odin's son will fight alongside with in "Thor: Ragnarok." While his fascination with Valkyrie is more like a fanboy, Chris Hemsworth admitted that Thor is "absolutely smitten by her" because she's a brave and strong warrior, but also because she's a "beautiful woman so he’s kind of caught off guard."

Valkyrie casting earned criticism

In the original "Thor" comic book series, Valkyrie is illustrated as a white, blonde woman.

In the screen adaptation of "Thor: Ragnarok," Valkyrie is played by Tessa Thompson, who is bi-racial and looks nothing like the comic book character. Director Taika Waititi stood by his decision to cast her in the role because they weren't concerned about the actress' looks and instead, on her acting ability and her ability to bring the character to life.

Chris Hemsworth also defended the casting choice, and told Bustle, "At the end of the day she was the best person for the job and when people see her play that character, they’ll absolutely agree. She’s pretty fantastic." "Thor: Ragnarok" opens on November 3.
