"I think I'd probably need to work on my French a little, but I'd be happy to try. A little Jean Seberg kind of accented French," she added, referring to the 1960s American-born screen siren.
Women in cinema
Portman, who in 2008 served as the youngest member of the 61st Cannes Film Festival jury, added that she would like to see more female filmmakers and pointed to directors Sarah Polley, Lena Dunham and Sofia Coppola as inspirations.
"You still really see that the majority of American filmmakers and writers are predominantly male. Which is great, I want men to keep making movies, but I'd love for there to be more female voices as well. And of course it influences the kind of material you read because the stories that a male perspective has, the way women figure into it, is very different," she said.
"You get a lot of girlfriends and muses and shrews. And every once in a while there's a magic moment where there's a really interesting perspective. My hope would be that they widen the access to women, and women are more inspired and encouraged to take on those kinds of roles."
Portman, who has a degree in psychology from Harvard University, also pointed to the defined gender roles on set: "You don't see female directors of photography, you don't see female technical crew members. Usually they're more on the hair and makeup, and wardrobe side.
"And it's more common to have all of the grips and gaffers and electric and camera, to be entirely male, which is just interesting."
If Portman has her way though, there won't just be more females on film sets -- but in science laboratories as well.
