Natalie Portman is worried people will get bored of her face because she is in so many new movies.

The Golden Globe winner is worried people will feel they have seen too much of her by the end of 2011 because she will be in a number of films.

"I did Your Highness and then Black Swan and then Thor and then No Strings. So it was really interesting. I feel bad for boring people with my face for a while."

However, the 29-year-old actress has a reason for doing it - she is concerned the end of the world is coming in 2012:

"You have heard that the apocalypse is coming, right? 2012. The Mayan calendar. I thought that I would get it all in right before. It was a great opportunity to get to do a lot of different things in a year. I feel like I learned so much from doing all these different types of movies, and back-to-back, because you bring the research and the seriousness and the discipline of doing a drama into something like Thor' and you bring the humor and the improvisational attitude from something like Your Highness into Black Swan," she joked.
