The first poster for the film showed up early this morning and then James Gunn told us this is only a preview, a full trailer will be coming soon!

The magic of the first movie is clear in this preview, and almost everyone is shown off in this teaser. Missing is the Mad Titan Thanos, and any of the new cast members. The full trailer should show at least some of the new cast.
