More Green Lantern Teased For Arrow Season 4
Marc Guggenheim took to his Ow.ly account to post an image of a Coast City billboard that reads:
In brightest day
In blackest night
Come to Coast City
When money's tight
Fans of Green Lantern will obviously recognize the reference to the Green Lantern oath.
There have been many references to Coast City and Green Lantern throughout the Arrow and The Flash Universe, with the biggest tease coming with mention of a missing pilot, another obvious nod to Hal Jordan.
Stephen Amell also recently stated it would be cool to have Green Latern as well.
Regarding WB not allowing Green Lantern for Arrow or The Flash, Guggenheim recently stated: "They announced the Green Lantern Corps movie, and I’d be surprised if it didn’t include Hal Jordan. It would be great but I doubt it very much.”
I suppose we can note Guggenheim didn't specifically state that they couldn't use Hal Jordan, just that he doubted it, so at least that does leave the possibility open that WB will let Green Lantern appear on Arrow and/or The Flash in some capacity.
