So, now that both Arrow and The Flash have aired their respective awesome premieres, we're not just excited for next week, or for Captain Cold, or even for Professor Zoom (why, yes, this is all code for "read my articles guys") - we're all excited about that crossover event happening very soon, Episode 8 of both The Flash and Arrow - "Flash vs Arrow," and "The Brave and the Bold".
But what should we expect? It's speculated that Robert Knepper will pop up as the Clock King, but from what I read he's mostly confirmed for Episode 7 of The Flash, not 8, which will constitute a dual-bad guy episode. It's known Captain Boomerang will, but we don't know how much.
What we do know is that the heroes fight, at least minorly. Set photos confirmed that, as seen below (thank you JustJared). Unless, of course, they misled us, which is far from unlikely.
Marc Guggenheim, executive producer of Arrow, also had some insight, labeling the crossover episode "freaking awesome," revealed in an interview with collider.com a little while back.
We have one of the biggest surprises on ‘Arrow’ of all time on ‘The Flash’ episode. And both episodes are really important for Barry’s growth… There’s a line in there that I will spoil because every time Grant said it, [I cracked up]. He goes, ‘When I fight you, it is literally like you’re standing still.’ And what’s hilarious about it is the unbelievable joy with which Grant delivers that line.
So, we seem to have some confirmation on that fight scene. He also said:
When we were working on the script, we realized that the best part of ‘The Flash’ episode was this meta commentary on how serious everyone is in ‘Arrow,’ and so there’s a lot of jokes at Oliver’s expense in ‘The Flash’ side of it. But then what was fun was when we went to do the ‘Arrow’ side of it, it became the reverse, where Barry and Caitlin and Cisco… all have to face ‘Oh wow, what you guys do is serious.’ So they’re sort of playing at a different level.
Which is great. The shows are stylistically different, and to ignore that wouldn't really be fair. Finally, on his own thoughts on the episodes:
It’s so freakin’ awesome! It really is. I’ve never had so much fun writing a script before, maybe in my life. It was such a blast to work on. We’re filming the Arrow episode right now, and it’s just so much fun. I keep telling everyone that we should try for Avengers. It’s these two heroes together with a big production value. We’re blowing out the doors on this. There’s the opportunity for inside jokes, and seeing all of the characters together. What happens when Cisco gets his eyes on Thea? There are moments like that, that you just can’t do in a normal episode. It’s just so much fun. It’s really going to be a blast. Jesse Warren is directing it, and he is just crushing it. Those dailies are really, really insane. Nick Tarabay plays Boomerang/Digger Harkness, and he’s amazing. And that weapon is a whole new visual language in the show, and a whole new visual language for our stunt guys to work with. And watching Grant and Stephen together is just magic.
Interesting that Thea will be in this episode, and set photos seemed to confirm that as well. Of course, we had to get set photos eventually. While rumors are great and the talk of the show is great, the greatest insight comes from a camera lens from the set itself, where the actors are all having more fun than we are (if that were possible). And what do they confirm?
The whole cast of both shows cross. Not one or two actors popping up or just the biggest leads, but literally everyone. It seems to be set in Starling - the Foundry, specifically- but who knows? Here are photos from everyone, ranging from Stephen Amell to Grant Gustin, and Emily Bett to Colton Haynes, and Carlos Valdes to Danielle Panabaker. Have a look. What we don't see are the likes of Iris West or Laurel Lance, though I imagine they'll pop up. Neither of them are particularly in on the hero action just yet - even if Laurel is getting close.
