Given how it was originally intended to be the start of it, I think we should include the 2011 green lantern film as a small page and add a category called non-canon
No, I don't think we should. It's not officially part of the universe, so we have no need to give it a page. It's already mentioned on the Hal Jordan page.
While also agreeing with JOAwesome, never was it stated that it was intended to be the start of the cinematic universe.
Well, It was only stated on Wikipedia, but anyone can edit that.
What do you think?
