For our purposes, the key point is that apparently Lassie's owners' intelligence is even more remarkable than Lassie's because they can understand dog language. Of course, they don't actually speak dog language back to Lassie because that would be beneath them, and Lassie needs to remember her place.

OK maybe Lassie shouldn't be expected to be able to speak English with her dog vocal cords. But what about the Chinese? Studies indicate that Chinese people may be capable of learning to make basic English sounds. But you wouldn't know it when they show up in movies. Take the Amazing Yen from the Ocean's Eleven movies.

He doesn't speak a word of English. Oh, he's understanding it perfectly. He just chooses to speak Mandarin, because it's a funny sounding language. Of course, Danny Ocean's entire crew understands everything he says perfectly despite never indicating that they can speak a word of it. I realize they're smart crooks, but every single one fluent in Mandarin Chinese? Really?

Star Wars does the exact same thing for a number of characters: Chewbacca, R2D2, Lando's weird little copilot.

They roar or beep or mumble gibberish and their English-speaking companions understand perfectly and speak English back to them. Han Solo in particular seems to understand every alien language out there, including Wookie-talk, Greedo-talk and Jabba-talk, which seems a little out of character since he doesn't seem like the type to listen to Rosetta Stone while flying around the galaxy. But f**k if he's going to talk to them in their own language. He's a space American and you're going to listen to him in space English or go home.

While that convention can sometimes works for real languages, it's usually a mess in outer space.

Take this scene from Babylon 5. You can tell both of those aliens are the same race because of their hair, but why does one of them talk like Dracula while one of them seems to be American? Are they actually speaking English in this scene or are they supposedly speaking Dracula? Is the whole alien race supposed to speak in Dracula accents? Is the American one a race traitor? Or is one guy from that planet's Transylvania and the other guy from that planet's America? I can't watch Babylon 5 too long without passing out from rolling my eyes too much but I don't think they ever really explain any of this.

Not only can screwing up fake accents make your show hilariously lame, you can even accidentally offend a whole race of people. In the Star Wars prequels, the Trade Federation creatures talk with what appear to be a racist's interpretation of a Chinese accent, which actually turns out to be a white actor's honest interpretation of a Thai accent. Add the fact that the Trade Federation is greedy and cowardly, a common old school stereotype of "Orientals," and you've got a recipe for offending a whole bunch of people you weren't even thinking about.

But when Worf is trying to teach his crewmates Klingon terms, how does he let the translator know not to translate them to English? Does he have to put verbal HTML tags around them? Take this exchange for instance ...

Why does the translator not turn "nib'poH" into "deja vu"? Does it have a slightly different nuance in Klingon? If so, you'd think at least 10 percent of words coming through the universal translator would stay garbled in alien, but almost every alien race the Enterprise meets can talk fluently with the crew with nary an untranslatable word or awkward expression. It's up to Data, the android who was made by and raised with humans, to humorously misunderstand simple expressions.

The Highlander TV series really takes the cake here though.

Duncan awakens a 2000-year-old Egyptian mummy whose first words are, "Does Rome still rule the world?" In English.

I realize the Highlander TV series is not where you go for historical accuracy, or any kind of accuracy whatsoever, but this is still a bit much.

We do this all the time. Pretty much every time you've seen an American actor pretend to speak Spanish or Chinese.

Americans don't usually notice. They accept that this super-spy or brilliant scholar is speaking flawlessly to the natives with their own language even though half the time, it's so badly spoken that the international version of that movie needs subtitles when it goes to that country.

To imagine what this looks like to them, think of Arnold Schwarzenegger. We had a thickly accented Austrian guy forced on us playing American soldiers, American cops, an American running man, an American killer robot and an educated genius who can speak 12 languages (all of them in a thick Austrian accent I guess), over and over again. Finally we got tired of it and put him into political office so he would stop.

Keep that image in mind when you consider how American audiences raved about Crouching Tiger, Hidden Dragon, while Chinese audiences winced as they watched Chow Yun-Fat and Michelle Yeoh, Cantonese speakers, stumble through their Mandarin lines. To non-Chinese speakers, the dialogue comes across as nuanced and flowing, while to a Chinese speaker, it is like watching Arnold Schwarzenegger's voice come out of a Chinese martial artist.

With all the hassle of representing foreign languages in movies, it seems like the only real solution is to stop having foreigners in movies. I'm personally looking forward to a refreshing epic retelling of how the Americans beat the Americans in World War II.
