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

The brunette beauty - who won a Golden Globe last weekend for her performance in Darren Aronofsky's psychological ballet movie 'Black Swan' - 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.

She said: "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.

She joked to Collider.com: "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 humour and the improvisational attitude from something like 'Your Highness' into 'Black Swan'.
