The filmmakers behind the English-language version of March of the Penguins—which is distributed by Warner Independent Pictures and National Geographic Feature Films—toned down the anthropomorphism of the original, French release（发行）.
March of the penguins 的英语版通过Warner Independent Picture 和 National Geographic Feature Films 联合发行，其制作人在影片中淡化了法语原版的拟人风格。
In the original documentary the penguins "spoke" their own dialogue, like Bambi or Babe the pig. The version released in the United States uses a narrator, actor Morgan Freeman, to tell the story.
原版电影中企鹅有自己的对话，就像Bambi 或Babe the pig 一样。美国发行的版本，采用了Morgan Freeman 朗读的旁白。
Still, the film describes the emperor penguins as "not that different from us" in their pouting（噘嘴）, bellowing（吼叫）, and strutting（昂首阔步地走）.
The bond（联结） between the star penguin parents is called a "love story." And the penguins seem to have emotions— grieving over the loss of an egg or a chick, rejoicing at the return of a mate, loving their families.
"In a few places it's a little over the top," said Alison Power, director of communications for New York City's Bronx Zoo and the affiliated Wildlife Conservation Society. "But I thought the filmmakers did an excellent job in not anthropomorphizing the animals."

Marine biologist Gerald Kooyman studies penguins at Antarctica's "Penguin Ranch," and he begs to differ. He said the portrayal of the penguins' mating rituals as a love story is a "major" case of anthropomorphism.
So do the birds experience emotions at all? "Zoologists would say, Probably not," said
Kooyman, who works for the Scripps Institution of Oceanography. "A lot of what looks to us like love or grief is probably hormonally driven more than some kind of attachment" to the egg, chick, or partner, he said.
For instance, there are several scenes in the film when a parent seems to grieve over a broken egg doomed（注定，命定） never to hatch（孵化）, or appears to mourn over the body of its frozen chick.
Instinct, hormones, and the drive to reproduce influence a lot of the penguin behavior, Kooyman said.
"What gives the impression sometimes of sorrow is that they fool around with the [broken or frozen] egg, or other birds try to take an egg away," Kooyman said. "There's just a drive to incubate, to participate in breeding behavior at that time of year for these birds."
The film also shows multiple shots of two adult penguins cuddling side by side, their beaks touching and forming almost a heart shape. It looks like love, but is it?
Despite the beautiful imagery, it's not certain that each posturing pair is actually a mated pair.
"If it's in August or September, the two are probably mates," Kooyman said. "In April it could easily be two birds that get together and then decide that they wouldn't make good partners.
"You also see such posturing at the ice's edge. There's a lot of social behavior between adults," he added.
Unlike nesting birds, penguin parents actually spend very little time together.
