The DC TV universe grew a little bigger earlier this month when it was announced that Supergirl and The Flash would cross over on the Girl of Steel’s show in late March. Barry Allen’s journey to Earth-2 in in “Welcome to Earth-2” showed that Kara Zor-El and her supporting cast live on another Earth, meaning it takes more than simple bus or plane ride for The CW heroes to meet her. Still, the potentials for more crossovers in the future are out there, and Stephen Amell wants in on the action.
During an interview with IGN, the Arrow star expressed interest in popping up on Supergirl at some point, wanting to add further contribution as this universe’s longest-tenured hero. As he put it:
Sure! In this iteration of the DC Universe, the ‘Television Universe’ as it were, I'm the guy that's been around the longest, so I always feel -- whether I'm on a show or I'm not on a show -- I always feel as though I can in some way, shape or form represent them, and I always want them to be wildly successful and last for many more years than we end up lasting, because I just want to see people have success. So I would love to go over to Supergirl. That would be a blast, if for no other reason than I miss shooting in Los Angeles.
Given how difficult it is to travel to parallel universes, the logistics of getting Oliver to Earth-CBS (or whatever you want to call Supergirl’s world) would obviously be complicated, even more so than Barry getting there. Still, an Arrow/Supergirl crossover would be interesting to watch, especially since Supergirl is a much brighter show than Arrow. Having a bow-wielding vigilante operating in Kara’s hometown and intimidating criminals would be a striking contrast to Supergirl’s normal way of handling things. Conversely, appearing in Supergirl would allow for Amell to possibly act more lighthearted and humorous, much like some of his appearances on The Flash. However Green Arrow and Supergirl team up, it would be cool if another Arrow hero, like Black Canary or Speedy, could also participate, assuming it doesn’t conflict with their schedules.
As for the first multi-network crossover, titled “Worlds Finest,” Flash will somehow make his way to National City, and while there, he’ll help Kara fight Livewire and Silver Banshee. Because Supergirl is on a different network, it’s unlikely we’ll get the same amount of crossovers as the CW shows, but assuming both Arrow and Supergirl are still on the air next TV season, don’t be surprised if both sets of showrunners try to work something out so Amell can jump on a plane to L.A. for filming.
Oliver Queen’s adventures on Arrow will resume Wednesday, March 23 at 8 p.m. EST on The CW, while Supergirl airs new episodes Mondays at 8 p.m. EST on CBS.
