"There are some performing animals that actually do have a more fulfilling life, but apes, you could probably say that's not the case," director Rupert Wyatt said. "In order to do what we need to do with them [in the film], you'd need to dominate and exploit them. I'd like to think that hopefully with performance-capture, we can bypass that and keep apes in the wild."
Yet "Apes" is more exception than the rule - Hollywood has been hot on live animals lately: The nonprofit American Humane Association, which monitors the treatment of animals in filmed entertainment, is keeping tabs on more than 2,000 productions this year, 100 more than in 2010. Already, a number of high-profile 2011 films, including "Water for Elephants," "The Hangover Part II" and "Zookeeper," have drawn the ire of activists who say the creatures featured in them haven't been treated properly.
In some cases, it's not so much the treatment of the animals on set that has activists worried; it's the off-set training and living conditions that are raising concerns. And there are questions about U.S. films made overseas, which sometimes are not monitored as closely as productions filmed stateside.
For studios, dealing with such questions is often a small price to pay given the box-office payoff for animal films. From the "Lassie" movies of the 1940s, to "Flipper" in the 1960s and more recent hits like "Free Willy" and "Seabiscuit," animal films often resound strongly with audiences, raking in huge ticket sales. "Marley & Me," which starred Jennifer Aniston and Owen Wilson as a couple who own a rambunctious Labrador retriever, grossed more than $240 million worldwide in 2008.
