Arrow: Guest Stars, Olicity, and Everything We Know About Season 4

Sadly for fans of NBC's one-season series Constantine, the canceled show was never picked up by another network. However, the character — who exists alongside Oliver Queen in the DC universe — is set to appear on Arrow! Matt Ryan will don the trench coat for the fifth episode of the upcoming season. Ryan confirmed the news in a video posted via Twitter, saying that "the rumors are true," and that he'll see us this Fall.

So many new people have joined the cast for guest or recurring roles! True Blood's Rutina Wesley is playing Liza Warner (aka Lady Cop); Enlisted's Parker Young is playing Alex Davis, a new love interest for Thea; and Jeri Ryan is guest starring as a politician in the second episode. Meanwhile, new heroes are on the rise! Echo Kellum is taking on the role of Mister Terrific, and Falk Hentschel is going to be Hawkman.

With new heroes coming, you had to know there would be some big bads to match. The season three finale sets up Damien Darhk as season four's potential supervillain. Since then, Neal McDonough was cast, and costar Paul Blackthorne shared a picture of him in character. He'll be in good (or should I say, bad) company, with Baron Blitzkrieg (Jimmy Akingbola), Anarky (Alexander Calvert), and Vandal Savage (Casper Crump), a character who will eventually move to DC's Legends of Tomorrow in 2016.

Oliver and Felicity go through an incredibly dark period during season three, but Olicity fans (myself included) rejoiced when they resolve to give their relationship a real chance on the finale. Arrow producer Marc Guggenheim is hopeful about the couple lasting, but he said in an interview that Oliver will face a huge challenge in balancing his relationship with his identity as The Arrow. The good news? "We're going to avoid, for as long as we can, Felicity being kidnapped," said Guggenheim.

Don't panic! Oliver and Felicity are totally an item, but newcomer Elysia Rotaru has joined the show as a love interest from Oliver's past. Her character, whose name hasn't been released, will appear in flashbacks. Guggenheim told TVLine that he thinks season four has the "best flashback story ever," so I'll be curious to see how exactly she ties in. At least we have a hint about what her character looks like; she Instagrammed this photo from the set.

The season four premiere, titled "Green Arrow," will air on Oct. 7!

Finally, The Arrow has a new suit! He has shorter sleeves, arm guards, and more leather. Of course, he has kept his signature arrows.
