While Marvel are doing a great job of keeping their film and TV universes connected - albeit loosely - DC have opted to keep their big screen endeavours separate from their small screen efforts. That hasn't stopped speculation on whether we might see some of DC's heavy-hitters show up in the Arrowverse, and Green Arrow himself, Stephen Amell was asked as much at a recent Heroes & Villains Fanfest convention.

Courtesy of ComicBook.com, here is his reply: "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'.", Amell continued. "So you never know."

While it would be awesome to see Green Arrow facing off against a small screen version of The Dark Knight, at this point it will likely remain a wishful thought. As to the winner of that hypothetical confrontation, Amell says he would be the victor: "What do you want me to say? Well, Batman’s more experienced and his costumes cooler, and Arrow’s just a ripoff, so Batman would win for sure. No, I would win, absolutely." Wishful thinking indeed.

Season 4 of Arrow airs on Wednesday nights on Sky 1 in the UK and on the CW in the US. Check out the trailer for the winter finale below...
