BBC presenters look back on their adventures throughout Indonesia and Mongolia, situated in earth's largest continent - Asia.Steve Backshall looks back on one particularly unnerving adventure in Indonesia, a place very close to his heart, where he and his crew were chased by the world's largest venomous lizards - a group of ravenous, three-metre-long Komodo dragons. George McGavin, meanwhile, recounts a slightly more sedate adventure in Indonesia: the time when he filmed in a school for orangutans in the middle of the Sumatran rainforest.Chris Packham also has fond memories of Sumatra, as he recalls how, in 1998, he took a batch of photographs of the Orang Rimba people, a group of hunter-gatherers who live in the rainforest. Wildlife cameraman Colin Stafford-Johnson also has an affinity with the archipelago; he looks back on his time spent filming Peanut, Hero, Tarzan and the rest of the monkeys that live on the island of Sulawesi.From the lush islands of Indonesia in the south of the continent, we travel north to the vast lands of Mongolia. Wildlife camerawoman Sue Gibson was sent there a few years ago to film Pallas's cats in one of the most physically and mentally demanding shoots of her career.
