yeah i agree with you there...
i was thinking that if Arrow/Flash are in a separate universe from the films, then they could use Ackles as Hal for that universe.
Green Lantern may be hard to pull off with a tv budget, but there is a solution... it just doesn't seem like something the studios would do...
I think WB should do a Green Lantern TV movie. They should spend as much $ on this 90 minute movie as they would spend on a season of Arrow or The Flash, because a GL story is basically impossible to do without a big budget. It'd be smart to first intro this Green Lantern in both The Flash and Arrow, but out of costume in both shows.
The stigma around direct to video movies or tv movies is unfortunate, there would most likely be a lot of bad buzz around the project, especially when compared to Marvel's film slate..i can imagine it now... "Marvel's making Ant-Man, while DC is doing tv movies?



"
a Green Lantern movie is probably really unlikely for a while, and Arrow is a high quality show with awesome writing, i would love to see a take on GL in the Arrow world. a tv show or a tv movie may be the best we can hope for as far as solo live action Green Lantern projects go. and honestly, tv or not, Arrow is damn good writing imo, and the acting is mostly pretty damn solid too. i have no doubt that an Arrowverse Green Lantern story would at least be better than the Green Lantern movie.
i think Green Lantern will be introduced in the MOS universe, but i'm not certain it will be Hal Jordan..But if GL is intro'd on Arrow or Flash, it'll definitely be Hal, given his connections to both Ollie and Barry
