Adriana Barraza In Talks To Join Thor

The Hollywood Reporter announced today that Adriana Barraza is currently in talks to play a part in the upcoming Thor film. 

  Details are scarce, but Barraza will play one of the humans. She joins a supporting cast that includes Anthony Hopkins, Rene Russo, Stellan Skarsgard, Idris Elba and Kat Dennings.
The movie begins shooting next week at Marvel's Manhattan Beach, Calif., studios. 

For those who don't know who Adriana Barraza ( imdb page), she was recently in Sam Raimi's Drag Me To Hell (see picture on the left) and also had a part in Babel. Most of her work consists of Mexican television shows and films. I thought she was pretty good in Drag Me To Hell, a memorable performance, if I do say so myself.  
 
Adriana, if she signs on, will play a human. But, who could she play? Is there any real characters, from the comic, that are human that she could play? Maybe she'll just be a film-only character? What do you guys think? Will she be a good addition to this already amazing line-up?
