Actress Anna Friel was left terrified while shooting a wildlife documentary in Africa when a huge gorilla charged at her.

The Pushing Daisies star headed to Uganda in August (13) to make a film highlighting the plight of mountain gorillas, but the trip almost ended in a nightmare for the Brit when a silverback primate turned on her.

Friel tells U.K. talk show host Lorraine Kelly, "We got charged by a silverback, which was, erm... okay! We were told to act passive and submissive but it goes against every single instinct in the body when you see a huge thing making a loud screeching noise... and you are not allowed to run. You have to stay and go, 'I'm a tree and there's a big thing running at me'."

She adds to Hello! magazine, "We heard this almighty sound as one crashed through the trees towards our photographer and came this close and then swung away again. It was like someone going, 'Yeah? Come on then,' showing their power and that it's their forest. My heart was pumping."
