Apparently the next DC animated films are another Batman film (Gaslight), a Suicide Squad film and a two part Death of Superman film. Suicide Squad is in continuity with the other animated films not sure of the Gaslight or Death of Superman is...
I'm only interested in the Suicide Squad film since I'm over Batman and we already had a DOS film back in 2007!
