Apparently, the film George Miller is said to be circling around out of the DC Cinematic Universe continues to be most commonly cited as MoS2.
So far only a story pitch is said to exist which has Brainiac hunting down Supergirl in search of the Codex that Superman is in possession of. Having failed to locate it he creates Bizarro and sends him after the man of steel.
No timing outline has been set for this but with such a busy slate it'd be 2019-2020 at the earliest.
