Natalie Portman has said she is talking with fellow actresses about "sharing salary details" to help each other negotiate over pay.

The 38-year-old Oscar-winner said being open about pay packets is currently "taboo" and urged women to talk about their income.

Speaking to Elle magazine, she said: "If we don't talk to each other, we can't share, we can't get information, we can't get angry and organise together.

"It's actually really important to talk."

"Something we've been talking about is sharing salary details with each other, because right now it's such a taboo."

"It's actually a real way that we can help each other, to be like, 'Hey, this is what I get paid. This is how I negotiated this'."

The actress's latest role is as an astronaut in Lucy In The Sky, which was produced by Reese Witherspoon.

Discussing how she picks roles now, she said: "I'm into women who are interesting to watch because they're as confusing, and confused, as we are.

"That's my favourite character to play: the one who messes up, but you understand what's going on to make her do that."
