One of the most infamous examples of animal cruelty in film was Michael Cimino's legendary flop Heaven's Gate, in which numerous animals were brutalized and even killed during production. Cimino allegedly killed chickens and bled horses from the neck to gather samples of their blood to smear on actors for Heaven's Gate, and also allegedly had a horse blown up with dynamite while shooting a battle sequence, the shot of which made it into the film. After the release of the film Reds, the star and director of the picture, Warren Beatty apologized for his Spanish film crew's use of tripwires on horses while filming a battle scene, when Beatty wasn't present. Tripwires were used against horses when Rambo III and The Thirteenth Warrior were being filmed. An ox was sliced nearly in half during production of Apocalypse Now, while a donkey was bled to death for dramatic effect for the film Manderlay, in a scene later cut from the film.
Cruelty in film exists in movies outside the United States. There is a case of cruelty to animals in the South Korean film The Isle, according to its director Kim Ki-Duk.[67] In the film, a real frog is skinned alive while fish are mutilated. Several animals were killed for the camera in the controversial Italian film Cannibal Holocaust.[68] The images in the film include the slow and graphic beheading and ripping apart of a turtle, a monkey being beheaded and its brains being consumed by natives and a spider being chopped apart. In fact, Cannibal Holocaust was only one film in a collective of similarly themed movies (cannibal films) that featured unstaged animal cruelty. Their influences were rooted in the films of Mondo filmmakers, which sometimes contained similar content. In several countries, such as the UK, Cannibal Holocaust was only allowed for release with most of the animal cruelty edited out.
More recently, the video sharing site YouTube has been criticized for hosting thousands of videos of real life animal cruelty, especially the feeding of one animal to another for the purposes of entertainment and spectacle. Although some of these videos have been flagged as inappropriate by users, YouTube has generally declined to remove them, unlike videos which include copyright infringement.[69][70]
