Tony Stark isn't the only one missing his girlfriend while appearing on screen. When Thor: Ragnarok rolls around in 2017, the God of Thunder will be missing his Jane Foster.

When asked by Empire Film whether the rumors of Natalie Portman sitting Thor: Ragnarok out were true, Marvel Studios head Kevin Feige simply responded, "I can confirm that, yes."

As for why, there are "many reasons," according to Feige. "Many of which are in the film so you will see that," he says. "There are only a couple of scenes on Earth in this movie. 80 to 90 percent takes place in the cosmos."

The exploration of the cosmos in Ragnarok will be no joke - something else Feige was willing to spill. "Tonally and geographically there are a lot of different planets outside of the nine realms that we visit in Thor: Ragnarok," the executie producer says.

Thor: Ragnarok is set for release November 3, 2017.
