The upcoming slate of DC Comics film adaptations is aiming for a consistent PG-13 rating across the board.
Producer Chris Roven confirmed this during an interview with Collider:
“Right now the movies that we’re making, the movies that have been announced by Warner Bros., I would say those are all intended to be PG-13 movies. I can’t tell you something may not come out of left field or we might get inspired to develop a different character, but the ones that are in front of us right now through [Justice League 2 are] PG-13.”
This does in Suicide Squad, which is perhaps the darkest and grittiest offering Warner Bros. currently has planned.
