The following are movies that entertainment sites say are in the works for DC:
1. Justice League. This seems to depend on how well "Man of Steel" does at the boxoffice.
2. Dark Universe a.k.a. Justice League Dark. Guillermo del Toro is producing this one. And all accounts that I have read make it sound like it will be very good.
Everything after that seems to be up in the air or being kept a secret.
The only other strategy that have heard is that DC plans to have other movies come out after Justice League. I also think that Dark Universe may do the same for properties such as Deadman, Swamp Thing, and Frankenstein.
More news as I see it.
Go Forth and Do Well.
