Hollywood's latest Tarzan Kellan Lutz has been caught on camera testing out his jungle call on gorillas at a zoo in Bristol, England.

The Twilight Saga star, who voices the legendary ape-raised jungle-dweller in an animated re-imagining of the story, visited primates at Bristol Zoo on Thursday (24Apr14) and tested out his character's signature yell on an open enclosure of gorillas.

He called out, beat his chest and moved like an ape with only a rope barrier and patch of grass between him and a giant silverback gorilla.

Lutz also showed off his jungle swinging skills on the zoo's rope bridge challenge during his visit in support of the Ape Action Africa conservation project.
