9. Setup Potential Spinoffs And Team Up Movies
When Batman and Green Lantern find themselves on the opposite end of Superman's strength, Hal call Barry Allen aka The Flash for a quick assist. During their conversation they discuss the last time The Flash and Green Lantern were seen in Central City taking down a talking gorilla, and how in the process they destroyed a museum, which resulted in the tarnishing of reputation. If there is one hero everyone has been waiting to see on the big screen it's the Flash. Barry is a crime lab technician, and Hal is an air force pilot; both have a mutual respect for one another as government authorities, but are also friends in and outside of the league. This quick conversation could lead to potentially a team up movie, or a better transition to the Batman vs. Superman movie.
