Another was with regards to the Justice League. It seems that we can expect things to branch off into an intergalactic opera with the introduction of the Green Lantern Corps.
The GL Corp will appear in the JL films, and this was confirmed by DC Chief Creative Officer Geoff Johns:
We’ve been to the bottom of the ocean, we’ve been to ancient Greek mythology, we’ve been to the past and future with the Flash, we’ve been to the digital world with Cyborg. We still got to go to space. So the Green Lanterns and the Green Lantern Corps are coming to join the Justice League universe.
Now that opens us up for an exploration of the DC Universe that goes upwards and outwards to the far reaches of space and beyond, maybe priming audiences before the Green Lantern film hits us in 2020.
