3. Green Lantern & The Flash

GL&F

Once again, this movie could be the perfect opportunity for Warner Bros. to merge their television and movie universes. Grant Gustin’s Barry Allen will make his debut in Arrow in a couple of weeks’ time before gaining the powers of The Flash and speeding off into his own series next year. While 2011’s Green Lantern failed to set the box office on fire, the possible success of Batman Vs. Superman could lead to Warner Bros. realising that team-up movies are the way to go moving forward. What’s great about these two is the fact that Hal Jordan is a cocky and brash adventurer who believes he is invincible, while The Flash is his polar opposite; a modest and clean-cut police scientist. Regardless, they put their differences aside and make one of the greatest teams in comics!
