Might not mean much, but I suppose it does offer Green Lantern fans a bit of hope.
Warner Bros. has registered the domain name for "Green Lantern 2."
This just means they own and control the url: greenlantern2.com, and no fanboy can run amuck with it.
However, that same day they registered "Gremlins 3" and "The Hangover 3," both of which are said to be possibilities, according to MovieHole.
Regarding a "Green Lantern 2" movie, we were told the Green Lantern sequel will definitely be better than the first as Sinestro will be the villain, and also that the sequel will act as the first step towards a joint universe in which hints towards other heroes can be integrated more easily.
Let's just hope it's better than the first.
