Talking about the follow-up to the Superman movie, Gunn stated that the characters we will see in the movie will feature the ones we have already met in Superman, and will meet before the follow-up film is released.
Well, this sounds promising. Hawkgirl hasn't been mentioned specifically, but it appears that not will she be appearing again in future Superman movies, but there is also a chance that a project involving her or the Justice Gang is in the works.
DC has yanked that football out from under us before, so I wouldn't hold my breath just yet, but when Hawkfans have to take what we can get, and right, no news or vague updates is better than a solid no. Wing crossed from a big announcement soon. First, I guess we'll have to check into the second season of Peacemaker and see if Hawkgirl has any more of a role than what we have already seen in the trailer. The Peacemaker series started today so check it out!
