With production under way onSeason 4of The CW’s hit seriesArrow, we have already gotten a look atTeam Arrow’s new high-tech “cave.” Earlier today, series starPaul Blackthorne, who plays Quentin Lance, revealed a photo from the set, which confirms that the name of Oliver Queen’s hometown Starling City has been officially changed to Star City. The actor is seen holding up his new Star City Metro Police badge, with co-starDavid Ramsey(Diggle) in the background.

You may recall that, atComic-Conlast month,ArrowstarStephen Amelltook to the stage, showing off his new costume, where he made a point to call Oliver’s hometown Star City, not Starling City. DuringSeason 3, Ray Palmer (Brandon Routh) mentioned changing the Starling City name to Star City as part of a rebranding effort, since the city had been constantly under attack by numerous villains. Now it seems it will be the official city name in Arrow Season 4. We won’t find out exactly why the name was changed until this new season debuts in October.

In the comics, the name was changed after the city becomes destroyed by earthquake machines and literally resembled a star when viewed from above. It remains to be seen if that specific comic book arc will be adapted for the small screen, but it’s certainly possible. This will be just one of many changes to the show, with Oliver (Stephen Amell) now going by Green Arrow instead of justArrow, along with the addition of several new characters.

Other new casting additions this season includeNeal McDonoughasSeason 4’s main villain,Damien Darhk, alongside Alexander Calvert as Anarky,Echo Kellumas superhero Mister Terrific,Jimmy Akingbolaas the villainous Baron Blitzkrieg,Jeri Ryanas Jessica Danforth, a new character that doesn’t originate in the comics, andJR Bourneas Double Down. AnotherDC’s Legends of Tomorrow,Hawkman(Falk Hentschel), will also first appear onArrowbefore the midseason series airs. In what is shaping up to be a highly-anticipated event,Matt Ryanwill guest star as John Constantine, reprising his title role from the now-canceled NBC seriesConstantine.

It is believed that John Constantine, who has expert knowledge of the Lazarus Pits, will be instrumental in the resurrection of Sara Lance (Caity Lotz), who will likely pop up in the fifthSeason 4episode alongsideMatt Ryan. Her character was killed in the Arrow Season 3 premiere, but it has been confirmed that she will come back to life as White Canary in the midseason spinoffDC’s Legends of Tomorrow. While we wait for more details about this resurrection, check out the latest photo from the Arrow Season 4 set below.
