No, this isn't one of my fever dreams regarding The Famous End of the World.
It's an A24 flick that, apparently, does what it says on the tin: it appears to be about USA Civil War 2, with a script written by the same cat who did 28 Days Later, Ex Machina,and some other more shit.
PLUS, our little A24 seems to be getting an IMAX release for.this one.
