London: Natalie Portman who won Oscar after playing a mentally retired ballerina in 'Black Swan' has no worries about starring in comedies now.

The 29-year-old actress, who will be seen as all-action Isabel in the forthcoming comedy film 'Your Highness' is glad to land up lighter roles and has no hesitations on shifting her image.

"The big thing I've been wanting to do is not be snobby and just do prestige movies, because that's really limiting - and it's joyless to do those kind of movies all the time. I don't want to fit into some mould of respectability”.

"Meryl Streep doesn't do the so-called 'right' kind of film all the time. Sometimes it's just about having fun. I think it's important to be irreverent and make a point of not meeting other people's expectations," said Portman.

The 'No Strings Attached' star also shared her exiting moments on the sets of the ‘Medieval caper’.

"Their dirty jokes made me laugh so much. I wasn't outraged, although they were scandalous!”

'Your Highness' which also stars actor James Franco and Zooey Deschanel has been scheduled to launch on April 8th.
