The Fourth Kind
The first time I heard about The Fourth Kind was seeing the trailer before District 9. I was into its Blair Witch meets X-Files vibe, but I stumbled on the part where the professor claims that an audio recording contains spoken Sumerian, "the oldest language in human history." From my memory of college linguistics, I immediately was like, "No fucking way do we know what Sumerian sounds like." The distance between spoken and written was still vast, with grammatical elements like verbs (much less morphemes) still in development. But then Wikipedia sorta proved me wrong by suggesting we can at least guess at the phonemes, though it's not exactly conclusive if we would be able to recognize spoken Sumerian. Linguists out there: please help!
