In Thor and Thor: The Dark World, Natalie Portman plays Jane Foster, a physicist whose work brings her into contact with Thor and Asgard.
Jane Foster doesn't get to do a great deal in the Thor movies, and doesn't appear (beyond brief references) in any other MCU movies. However, in Avengers: Endgame, Foster
appears once again, apparently played by Natalie Portman, but literally just gets to have a short conversation in a far-off doorway, and get out of bed, totalling less than 10 seconds of screen time.
Are there any out-of-universe comments from anyone involved discussing why the role was so limited?
