A blog site Canadagraphs has behind the scenes photos and some fan filmed footage from when the Arrowverse shows shot in public in Vancouver.
He has strict rules limiting copying his exclusive photos so I will just post a link to his blog. Warning there could be spoilers about the Crisis and other Arrowverse shows on the blog.
Here is a link to a nice group photo. I couldn't find a version that would let you to copy it. First I have seen that includes Black Lightening and Ryan Choi (Atom) https://www.instagram.com/p/B3cCgL9ntww/
And another picture. I have noticed there have been no pictures with Stephen Amell with other characters yet. Just Crisis photos of him by himself .
It's got to be logistically challenging to work Black Lightning in, given that that show shoots in Atlanta while the rest of the shows shoot in Vancouver. I wonder if Jefferson is the only character crossing over, or if we'll see his daughters too.
Latest rumors:
The universe of the Tim Burton Batman movies will be referenced.
Tom Ellis will appear as Lucifer Morningstar.
The producers are seeking to include characters from "Titans" in the crossover event.
The cameos with the characters from DC shows past will most likely be at the beginning of the first episode of Crisis with a bunch of them looking up to see the sky turning red from their various Earths which will be the sign that the Crisis has come. Hope at least Lois and Clark from Smallville get a story. Red sky over Central and then Star City was referenced during last year's crossover. This fits with the picture of Burt Ward. Titans appearance will most likely also be cameos from this opening. They film in Toronto so they will stare at the sky from their set and be cut into the opening. No pictures yet of a lot of the supporting players from the various shows. Will they be MIA or just appear briefly on their own shows. For Legends I was hoping for appearances from all the characters who have left the show including the Hawks, Prof Stein, Jax , Captain Cold, and Rip Hunter. Hopefully they will save some appearances as a surprise.
It seems like SUCH a massive undertaking. I've pretty much dropped all of the DC superhero shows from my line-up, but I WILL be tuning in for this. It's too unique to miss.
In particular, "Arrow". "The Flash" is building toward Crisis, but it has its own non-Crisis related Big Bad to deal with in the meantime.
On the other hand, it feels like this entire final run of "Arrow" will be about laying the groundwork for Crisis. Also, if the rest of the season keeps up the same quality as the season premiere, it's going to be one hell of a ride.
Marc Guggenheim confirmed on Twitter that Adrian Chase is actually the second Hood on Earth-2. He took over from Robert Queen, presumably following his death or incarceration.
He also confirmed that Earth-2's Batman did indeed spend time on Lian Yu.
Any more scoop on the Arrowverse’s “Crisis on Infinite Earths” crossover? –Derrick The question of exactly which Lyla Michaels (ours, or another Earth’s) will be assisting The Monitor as Harbinger will be answered “pretty fast” — specifically, in Arrow’s third episode, says showrunner Beth Schwartz.
