sentences:  In 2011, National Geographic made a second documentary called "Tiger Man of Africa".The project was the subject of controversy after accusations by investors and conservationists of manipulating the behaviour of the tigers for the purpose of the production of the film "Living with Tigers", with the tigers believed to be unable to hunt.Stuart Bray, who had originally invested a large sum of money in the project, claimed that he and his wife, Li Quan, watched the film crew "[chase] the prey up against the fence and into the path of the tigers just for the sake of dramatic footage."
