Three separate Hollywood starlets have made headlines today for voicing their opinion on a number of issues.

First up it's Natalie Portman, who's slamming Hollywood for being entirely misguided and incorrect to portray women as 'kick-ass' and 'strong' primarily when they're kicking ass in movies. She's a firm believer that vulnerable and weak female characters can contribute towards feminism too, because they are, too, realistic. In an interview with Elle Magazine, Natalie says: "the fallacy in Hollywood is that if you're making a 'feminist' story, the woman kicks ass and wins... That's not feminist, that's macho. A movie about a weak, vulnerable woman can be feminist if it shows a real person that we can empathise with."

Elsewhere, Heather Graham is shedding light on Hollywood's longstanding history of sexism, via Women's Health: "The industry is totally sexist. It's run by men mostly," Graham said of Hollywood... Look at the movies that are coming out. How many are about women? If you look at who the leads are, they're probably 75% men... A woman being able to express her sexuality is the ultimate form of freedom. In American culture, I feel like women don't have the safety to express themselves sexually."

Which leads us nicely to what Scarlett Johansson's been spouting about porn: contrary to the widespread female thinking that pornography is degrading towards women, she reckons it can, on ocassion, be quite liberating too. Scarlett stars opposite Joseph Gordon Levitt in Don Jon, as the other half of a man suffering with porn addiction.

"In the film it is the element that destroys the relationship. Pornography can be degrading or can be sexually liberating, if you know how to use it and it is made from an artistic point of view.

"But Don Jon is not a film about pornography, it is a social criticism against consumerism."

So, do all these ladies have a point? Share your thoughts in the comments box below.
