While comic book fans already loved Natalie Portman in the Wachowskis' take on Alan Moore and David Lloyd's V For Vendetta and are looking forward to her playing Jane Foster in Kenneth Branagh's Thor, the critical and awards heat she's been getting for her role in Darren Aronofsky's Black Swan has put the 17-year acting vet's name on everyone's lips. Two of the many movies she's been rumored to be in line for are Warner Bros. and DC Entertainment's upcoming tentpole movies, Zack Snyder's Superman: The Man of Steel and Christopher Nolan's The Dark Knight Rises.

In an interview for this week's Oscar issue of Entertainment Weekly, Portman denied the rumors about her appearing in either (or both) films.

When asked about Superman, she told them:

"What is that? (laughs) No, I haven't heard anything."

And whether she'll appear in the finale of Christopher Nolan's Batman triptych:

"Oh, I don't know anything about that."

Of course, the press-savvy Ms. Portman could just be playing coy, but unlike so many other less-experienced actresses who are asked about casting rumors on the red carpet, she's clearly so on top of her own career that if there were offers for her to be in either one of those superhero franchises, she would already know about it.  This doesn't mean that someone at Warner Bros. (or the respective filmmakers) haven't thought about approaching her, though one can expect that would wait until they have a final script and if she does get cast, it will be big news.

Either way, for now, the earlier rumors are just that. Rumors.
