Whoa. Your interpretation is off, GT.
I can see by the way I worded it how one might get that impression. However, saying "A hint of ethnicity that I can't put my finger on" isn't the same as saying "Not white, but ethnic". Maybe "A hint of an ethnicity" would've conveyed the message better. Long story short, not racist. Who knows? If I'm a "bad person", it's not for that particular reason.
But yeah, super-psyched about this movie.
