The first trailer for Arrow’s return introduces a whole lot of new elements, and reveals how Oliver and Felicity return to the fold.

The Season 3 finale functioned almost as a series ender, so the new season has a lot of work to do in resetting the board. Boy, does it ever. The trailer gives us a peek at the life Oliver and Felicity have built in the wake of last season, then shows off how Team Arrow is working sans Arrow. The ladies have really stepped up, and Diggle seems to be the new man in charge.

We also get a peek at Matt Ryan’s eagerly anticipated cameo as Constantine, Diggle’s new costume, Sara Lance’s resurrection and Damien Darhk’s introduction as the new Big Bad. It’s only a few scenes here, but Neal McDonough definitely seems to have the gravitas to pull off his role as the new villain for the year. Needless to say, it’s going to be a busy fall in Starling Star City.

Check out the new trailer below and let us know what you think:
