Re: Will Natalie Portman reprise the role of Jane Foster?
The way they could fix the Jane issue with the movie taking place mostly in Asgard is to go all Alice in Wonderland with it. Thor is reunited with Jane after the events of the Avengers and she asks his to take her back with him to Asgard. She doesn't really have to be part of all the action, but she could hang around with Frigga I guess.
Natasha Romanoff - "Are you boys really that naive? S.H.I.E.L.D. monitors potential threats."
Bruce Banner - "Captain America is on threat watch?"
Natasha Romanoff - "We all are."
