SPEAKER: Three, two, one, action!
We've always had really good sets,
but they really were elevated this season.
You walk in and you're like, "Wow, this is epic in scale."
As you can see, everything looks fantastic.
We get to explore new locations that exist in Metropolis that
we otherwise have never seen before.
What I love about this season is how we dive into horror.
We have blood, knives, a lot of the horror imagery
that we hadn't been able to use before
that we used in season one with Raven,
but we haven't been able to go back to it.
And that has been a lot of fun on a technical level,
and exciting on a storytelling level.
JOSHUA ORPIN: Metropolis is the birthplace of Conner.
It's the home of Superman.
It's also the home of Lex Luthor.
And in contrast to Gotham,
it's kind of perceived as, I guess, a lot brighter,
more hopeful place to be.
It's a city that looks to the future, and there's beautiful parks,
and Superman's flying through the sky saving people.
We really believe that coming out of season 3,
which was emerging from the darkness of Gotham,
that the Titans needed to move towards light.
And in the DC world, Metropolis is light.
There's a long history of Toronto being
kind of the visual model for Metropolis in the books.
KHANH GUACH: We have lots of tall glass buildings, clean lines, great architecture.
But to create Metropolis, we have to find its identity.
And to me, Metropolis' identity lies within S.T.A.R. Labs.
♪ (UPBEAT MUSIC PLAYS) ♪
Built by Garrison Slate in 1971.
JAY LYCURGO: That was my first line that I learned about thirty times.
There's a lot of it. (CHUCKLES)
S.T.A.R. Labs is like the tech center of the DC universe.
It's the most super secret, coolest Apple lab
you wish you could see that you've never been to.
The comic book version has more of a rectangular, boxy shape,
whereas ours is more of a circular environment.
We wanted to just really represent the galaxy and space which is all about Superman.
The under-lit floor of the set is actually a re-use
of Deathstroke's floor set in season two.
We made it from a square shape to a round shape.
It's such a useful piece to have to light our space and actors.
LexCorp Tower is also a very high tech place,
but it serves a different purpose compared S.T.A.R. Labs.
If S.T.A.R. Labs' mission is to help humanity,
LexCorp Tower is there to take over humanity.
There's this really amazing drawing of Lex Luthor
in his glass box office overlooking Metropolis
like a villain looking over his own kingdom, in a way.
And that's where we started the design of LexCorp, essentially.
The space feels large. High, tall ceiling.
But there's a sense of loneliness in the space as well,
and it's cold, and it's foreboding.
That set was beautiful, and the view is just ridiculous.
Like, the most beautiful Toronto view I've ever seen.
GREG WALKER: Whenever there's light, there's gotta be darkness.
So we start to see the other side of Metropolis.
GROUP: (CHANTING) Azarath! Metrion! Zinthos!
Welcome. This is the Temple of Azarath.
The Temple of Azarath was definitely the coolest set we've had this season,
maybe in the entire history of the show.
The feeling you get when you walk in is palpable.
It's a hellish place to be in.
The Temple of Azarath has this pool in the center of its stage
that just looks like a cauldron of hell.
(CHUCKLES) Like it's where Brother Blood goes into and comes out dripping.
GUACH: The Temple of Azarath lies in the underbelly of Metropolis.
In the comic book version, it's not evil at all,
because it is Raven's birthplace,
but in ours, this temple has been corrupted by Trigonic magic.
In the DC comic books,
Azarath has these beautiful golden raven sculptures in the temple.
Because our version of the Temple of Azarath is a lot darker,
so why don't we take those ravens
and turn them into something even more demonic.
The temple's actually a refurbish of the Bat Cave from season three.
And we used the exact same rock wall, and we changed the color.
WALKER: What Khanh was able to do was build in all these symbols of the cult
inside the lighting scheme that goes up to that big, round pool of blood.
My favorite set this season is the RV set.
Spoiler alert, we're not actually in an RV.
We built a set.
There's a lot of opportunities for travel,
and for us to appear like we're on the road,
but we're really in the studio.
It's so fun to be able to explore these imaginary cities that fans know so well.
This season in particular, I like the look of a bit more
because it's not as just dumpster fiery.
(CHUCKLES) It's refined fire.
It's beautiful, Trigonic fire.
Last season was gritty and Gotham,
whereas this season, it's really magical and underground.
WALKER: What I love is watching our Titans together.
I never get as excited as seeing all of them walk into frame, standing by each other.
You're like, "Wow, they are cool."
