Batman: The Killing Joke is going to be the first R-rated Batman movie ever. Don’t think it doesn’t count because it’s animated. The last several DC animated films have been really dark and amazing while pushing the boundaries of their PG-13 rating.
Anyone who grew up in the 90s should be stoked for this because they are bringing back Kevin Conroy and Mark Hamill to voice the lead characters. Both actors did the voices from the ‘still greatest cartoon series of all time’ Batman: The Animated Series.
