Topic: Justice League trailer
It was certainly a trailer for a movie. That's a fact.
What I know about this movie from the trailer:
1.) It'll be a movie
2.) It'll likely be longer than the trailer
3.) It'll probably be 24fps
4.) It'll star J.K. Simmons
5.) Cyborg has AT LEAST one line of dialogue
6.) Warner Brothers successfully hired an editor capable of matching gunfire in the movie up with music.
