Steven Amell believes that one day, both Superman and Batman could turn up in either Arrow or its spin off The Flash.
Batman has already been referenced in The Flash as of being connected to Oliver Queen in the future, but fans have been hoping that The Dark Knight will one day make an actual appearance. With a rouge of villains usually associated within Gotham City, turning up in the last three seasons in makes sense if Bruce Wayne does as well, but DC have in the past dealt a frustrated blow to the writers of the hit show, denying them access to the likes of Harley Quinn who was due a pivotal role in season two.
Also with Gotham proving a massive TV hit and it having no connection with the Arrow universe, we very much doubt that this will happen, but Amell believes anything is possible.
“Well, I mean, the short answer is yes, of course. Within the DC Universe, if they are in the DC Universe, if you were to ask if Iron Man could come to Arrow, I would be like, ‘Well, no, probably not” Amell replied when asked the question. “But of course, The Joker could come to Arrow, Batman could come to Arrow, Superman could show up on The Flash. There’s a whole myriad of options because again DC and WB have a slate of films coming up, and those films happen, and maybe Arrow’s still around when they’re done. Or maybe there’s a change and people are just like, ‘You know what, let’s invest in something that’s doing well for us.’ So you never know”
Could Arrow and Batman or The Flash and Superman team up on the small screen? Lets put this down as a very unlikely possibility.
