很难相信DC电视帝国已经从2012的绿箭开始发展的那么大了。同一个世界观下已经有2部衍生剧，闪电和明日传奇。而且，越来越多的交叉集也构建了这个宇宙。绿箭和NBC短命的康斯坦丁统一了世界观，CBS的超女也是多元宇宙的一部分。

　　本周已经放出了闪电出现在超女中的一集了。世界上最快的男人意外的闯进了超女的世界，开拓了比绿箭营造的世界更加广阔的世界观。如果反响不错，这种事应该会被再现。

　　华纳兄弟似乎也是那么看的，已经在协商一个有可能的交叉集，这次是FOX的哥谭。这消息被TVLine放出而且迅速被FOX官方确认。闪电可能出现在哥谭221中，闪电的制片人 Greg Berlanti说“我们对此能和FOX和哥谭团队合作很兴奋，当闪电进城的时候，哥谭的大坏蛋不会知道是什么打了他们的!”

　　It’s hard to believe just how much the DC TV empire has grown since Arrow debuted on The CW in 2012. There now two spinoff shows on the network that are set in the same universe –The Flash and Legends of Tomorrow. Furthermore, crossover episodes with DC Comics-based shows on other networks have confirmed that Arrow takes place in the same world as NBC’s short-lived supernatural series Constantine, and that the Arrowverse is part of a multiverse that includes CBS’ Supergirl.

　　That latter bit of canon was confirmed by this week’s appearance of the Flash (Grant Gustin) in the Supergirl episode ‘World’s Finest’. The Fastest Man Alive accidentally jumped through a portal into Supergirl’s world, and in doing so established a precedent for bringing TV’s further-flung DC shows into the Arrowverse fold. And if the ratings spike that Supergirl enjoyed is anything to go by, this is an experiment worth repeating.

　　Warner Bros. TV seems to think so as well, as it looks like another crossover has been negotiated – this time with FOX’s Batman prequel series Gotham. The news was broken by TVLine and quickly confirmed in an official press release by Fox, which states that Gustin will make a guest appearance in episode #21 ofGotham‘s second season. The Flash executive producer Greg Berlanti said, of the crossover, “We’re so excited to be working with FOX and the Gothamcreative team on this episode. The villains of Gotham City won’t know what hit them when The Flash rolls into town!”
