It's been thought that Natalie Portman might be done with Marvel and her Jane Foster role.
However, Thor: Ragnarok director Taika Waititi has now seemingly teased Natalie Portman for Thor: Ragnarok.
Taika Waititi took to Twitter to post images of Natalie Portman along with "Heed the signs" and the #Ragnarok hashtag.
I guess it's possible Taika Waititi could simply be making a joke, but since Natalie Portman has been said to be at odds with Marvel over Thor: The Dark World and the leaving of director Patty Jenkins, the joke really wouldn't be in good taste.
Some fans online are also joking it's a reference to Jane Foster taking care of Groot.
Natalie Portman did say she would be open to return to Marvel, but Marvel Studios president Kevin Feige did imply Portman won't be in Thor: Ragnarok as Jane Foster and Thor have broken up. Maybe they made room for a cameo?
Taika Waititi also posted some sort of strange Thor 3 lemon video recently.
