Four years ago, no one expected that the Arrowverse would become what it is today: a connected network of multiple series that embrace the fun super heroics of its source material while delivering epic action on the small screen. Arrow especially has come a long way from just being a color swapped Batman Begins, and though we see lesser known characters like the Atom or Vixen, it doesn't mean the bigger kids can come out to play. Fans shouldn't expect for Green Lantern to appear anytime soon.
In an interview with CBR for Arrow's 100th episode, executive producer Wendy Mericle was asked if Carly Pope's Susan Williams was brought in specifically for her connection to the Green Lantern mythology.
One of the fun parts of the show is that you can put these characters in and the Easter eggs and the fans that know this universe so well respond to it on varying levels of excitement and whatnot, but the thing about her character that's so intriguing is that it operates on that level. It also operates because she's someone who's very intrigued by Oliver, who's going to uncover some secrets that Oliver has, which is going to be really fun, and is a fun nod to the Green Lantern, who obviously we could never bring on the show.
In the comics, Susan Williams is the sister-in-law of Hal Jordan, and it sounds like the tease of her connection to the character will remain just that: a tease. Over the years, Green Lantern has been teased on Arrow more than any other member of the Justice League who isn't the Flash. Hal Jordan's home turf Coast City and his place of business Ferris Air have continually been named dropped. There's even a blink and you miss it easter egg of a flight jacket with a name tag that reads "Jordan" at one point. These easter eggs are generally pretty fun, but it sounds like we won't be getting anything substantial from Green Lantern.
But don't throw in the towel just yet! Five years ago no one thought we'd even be having this conversation, let alone the idea of seeing Green Lantern on TV being feasible. Superhero shows have come a long way; while Hal Jordan and his Corps may be a pipe dream who knows where we'll be when Season 6 rolls around. If aliens can invade Earth in a four-way crossover then really anything is up for grabs.
It's true that the DC TV shows aren't allowed to use characters that the movies have bigger plans for, but that could be changing. Yeah, we don't have Deathstroke or the Suicide Squad anymore, but Superman was just in two episodes of Supergirl, so there's room for exceptions. I don't see why Hal Jordan can't stop by for a quick road trip through America with Oliver and also be on the big screen.
