Angelina Jolie has learned a new language of love.
"I love speaking Russian. It's very, very hard. I find it a very interesting sound because it can be so hard and strong and also very sensual and very beautiful," says Jolie, 35, who picked up the language for her new spy thriller, Salt (out July 23).
Added Jolie (who spoke at a weekend event to promote the flick), "It's a very interesting sounding language. It took me a long time. I just had to practice over and over and over and I was told that I was getting it wrong a bunch of times and I had to keep practicing."
Jolie worked with a Russian vocal coach. "They'd do it with me, spend time with me and then they'd put it on tape. So I would take it home and I would just keep trying to get it exactly right and then trying not to get so stuck on a line."
The actress says speaking the language on-screen added sexual tension with co-star Liev Schreiber, who can read Russian.
"It was interesting to see how seductive that language could become when we were doing it… that some sounds can really hinder that or some accents have a very specific feeling to them," she says.
Jolie admitted in the new issue of Vanity Fair — an article she said over the weekend she has not read — that she'd like to retire from acting in the near future.
"I just imagine in the years to come… it's not that I'm retiring, but there will be less films at some point and I'd love to do other things. I'd love to live in Africa for six months and fly planes," she said.
Jolie looks forward to growing older, she says. "I do think that age is beautiful."
For now, she stays young chasing her kids with Brad Pitt, 45, around their house.
Twins Knox and Viv — who turn 2 years old Monday — "are going in different directions at the same time," she jokes. "We have put a lot more gates around. We've gated off a lot of the rooms in the house where they were going."
The other kids — Maddox, 8, Pax, 6, Zahara, 5, and Shiloh, 4 — "are all over the place."
"Zee is the fastest in the house," adds Jolie.
