Not a confirmation, but Dwayne Johnson really wants Patty Jenkins to be the director...yeah, I'd be down with that.
I doubt there will be fatigue, outside of one underperforming film here and there, but 2018 definitely feels like the peak for SH box office gross, at least within the next few years.
