What they didn’t report on was Flash Vol 2 #30 from September of 1989. The story starts out with the Flash getting into an argument with his mother, then he takes his best girl to a movie. remember, this was 1989 and the first Batman with Michael Keeton had just came out.
You can see on the marquee behind her that one of the movies is Batman. Underneath Batman, you can see that “One Flew Over the Cuckoo’s Nest” is playing as well. That film starred Jack Nicholson as an inmate in a mental institution. Nicholson would go on to play the Joker in the first Batman film. On July 20th 2012 in Aurora Colorado, a man believing himself to be the Joker opened fire on a crowd who had come to see the premiere of the new Batman movie.When a bullet presses against Wally’s neck, his super speed kicks in. He is able to run around the theatre at super speed and pluck all the bullets out of the air, and then dispose of the gunman. So in this comic published in 1989, the Flash stops a shooting in a movie theatre that is showing the new Batman movie.
I do think there is something supernatural at work here. Comic Book writers are sometimes able to pick up on future events and publish them before they happen.
