Lizard people from the center of the earth that masquerade as politicians is a well known fact.
I assumed that thing in the background was an artificial sun. I’m a fan of Starcraft through proxy (wife plays it so I do too), but I assume they’ll keep things strictly mainstream this time.

As for the first movie, it was fun idea but incredibly clumsy – felt like everyone involved was doing it for the first time.
