Roland Emmerich Is Planning Two Sequels To ID4

/Film brings us the following from Emmerich:

That’s actually what we talked a lot about. The mythology of why did the aliens come in the first place, what is the bigger story of this whole thing? And we talked a lot about swarm intelligence. And [the humans] are individual intelligence. Even though we kill each other and have wars against each other, we have something special. We have this domino human spirit to believe in good and over coming enemies. And it’s a little bit about that and when you get a bigger mythology going, I think then you have the chance to do not only one or two or three but you can create a series and that’s what we want to do.
