Don't know. With the original line-up of films and JL I assumed we were going New 52 Justice League (Superman, Batman, Wonder Woman, Barry Allen, Hal Jordan, Aquaman & Cyborg).
I think Titans may work better as a show tbh, but I have nothing against them making a movie either. However, I am conflicted. I love pre-52 Titans, but I love the idea of Cyborg being a founding member of JL now. If they can find a way to bridge these, I'm happy.
