The one in the Mao hat.
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?
Even Scott Caan?
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 fuck 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.
This may be how aliens see Han.
