While technically not part of the Arrowverse, it comes as no surprise that Supergirl will lead the charge in the huge four-show crossover on The CW. But, there’s a bit of a catch, which we will explore in this article.
When recently speaking with Entertainment Weekly, Arrow and DC’s Legends of Tomorrow executive producer Marc Guggenheim stated how the inter-dimensional barrier separating the Girl of Steel from the other heroes wouldn’t pose much of a problem before going on to say how they arrived at a solution, effectively getting her to join the fight against the invading Dominators:
“Last year, Supergirl established that Flash was able to make his way to what I call Earth-CBS, and it stands to reason that, with the proper breach technology, the reverse can happen.
“Once the heroes realize that they’re up against aliens, they decide that they need an alien on their side. Fortunately, Barry knows a really nice one. I don’t think it’s a big shock that between Barry and Cisco, and all their experiences with Earth-2 and the multi-verse, that they can pluck her from Earth-CBS.”
Furthermore, Guggenheim went on to elaborate on how it’s more so the character of Supergirl taking part in the event and not necessarily her show itself:
“Some people call it a four-way crossover because it involves four shows; my ulcer requires me to call it a three-part crossover. The story that’s being told has a beginning, middle, and end: a beginning in Flash, a middle in Arrow, and an end in Legends. But Supergirl is very much a part of the whole thing, so we are crossing over four shows — four shows in three parts.”
In the midst of all this, Arrow will advantageously celebrate its 100th episode aired. But fear not, because despite it taking part in a crossover, the show will not lose its sense of identity:
“When the news broke that the 100th episode was also going to be the crossover episode, people were up and down my Twitter and Greg [Berlanti’s] Twitter I think, in this case, in a very positive way. People didn’t want to feel like the crossover was highjacking what should be a really seminal episode and a seminal moment for the show Arrow, which I think is wonderful. Greg came up with an idea that really does allow us to have our cake and eat it, too.
“I haven’t seen the episode all cut together yet, but it has some incredibly iconic moments. It is a love letter to the show, it draws on all previous 99 episodes pretty much. Everyone who we could have in the episode, from a scheduling point of view, is in the episode. Even the people who we couldn’t have, because of conflicting schedules, are represented. At the same time, you’ve got Flash and Supergirl; that’s an enormous amount of fun. Certainly the recruits also play a very large role, an important role, in the episode. I’m really excited about it.”
Expect Supergirl to get the ball rolling in late November or early December.
