Natalie Portman was on hand at the 2013 D23 Expo Saturday (Aug. 10) to help Disney promote its live action slate, which includes her forthcoming "Thor: The Dark World," Marvel's sequel to 2011's "Thor." 

Marvel president Kevin Feige gave "Thor 2" fans  a sneak peek at footage that showcased Portman's character, Jane Foster, experiencing her first day in Thor's world of Asgard.

Backstage, we wanted to know what the actress' reference was for portraying her character in such an awe-stricken situation. 

"It wasn't hard because I was having those feelings myself," Portman tells Zap2it. "The sets were so magnificent, and all of the people were so beautiful, in their beautiful clothes. It was pretty natural to just have my jaw dropped the whole time."

And while her character is portrayed in the recently released "Thor 2" trailer as a but of a bruiser -- she lands a right hook on Loki ( Tom Hiddleston), after all -- Portman plays down that aspect of the film. "She's a mere human in Asgard, where they're all superheroes," Portman says of Jane. "So, they sort of put her to the side while they do the butt-kicking."

Since Thor was featured in 2012's "The Avengers," along with cast that spilled over from other Marvel Cinematic Universe franchises -- Tony Stark ( Robert Downey, Jr.) and Pepper Potts ( Gwyneth Paltrow), among them -- we had to ask Portman whether Jane might eventually follow Thor to "The Avengers" franchise. "No," Portman says without hesitation. "No, no no." Well, she's missing out.

"Thor: The Dark World" is in theaters Nov. 8.
