Weird, I watched this 2 nights ago.
I came up with a theory that the scientists were the last people on earth.
Windows starts the movie talking about how they haven't reached anyone via radio for 2 weeks - maybe the thing had already taken over earth and the scientists in Antarctica were the last remnants of humanity?
I guess that doesn't jive with the spaceship the Norwegians found, but idk
I always thought Venice looked like a handshake.
