Portman films Rwanda gorillas documentary

Natalie Portman has filmed a documentary about rare mountain gorillas in Rwanda.

The actress joined animal expert Jack Hanna to shoot Gorillas On The Brink, part of Animal Planet's Saving A Species series.

She told TV Guide: "They asked me to go to Rwanda with Jack Hanna to interact with mountain gorillas. We spent five days in Rwanda, then I continued on to Kenya for an eco-safari.

"The gorillas are very endangered. There are fewer than 1,000 left. And they're still being poached. They kill adults and sell babies on the black market."

Portman, a long-time vegetarian, revealed that she stood five feet away from the animals, saying: "But we couldn't touch them because they catch cold so easily. On our first day out, we happened upon a lone young silverback male sitting right in our path!"

She added that the highlight of her trip was naming a baby gorilla, which she described as "an honour". She added: "I named mine Gukina, which means 'to play'. All the babies were so playful."

Portman will next appear in Mr. Magorium's Wonder Emporium with Dustin Hoffman.
