- Hi, MTV News.
I'm Camila Mendes.
- Hey, guys, I'm KJ.
- My name's Casey Cott.
I play Kevin Keller.
We are currently shooting the biggest
musical episode TV has ever seen.
♪ Tommy, lately I've just not been feeling right ♪
I don't think it's a coincidence that we ended up
doing Carrie the musical in Riverdale High.
I think it makes perfect sense that they would do that.
There are a lot of parallels between
each character that our characters play.
Betty plays Sue and Archie plays Tommy
and Veronica plays Chris.
It works very well in kind of a strange way.
- Having Roberto as our showrunner,
who has a massive background in musical theater,
I think it's not too surprising.
And he also worked on Glee too,
so I think we're in really good hands.
- I think Chris was a dream role
because she has that song, According To Chris,
and that's like the fierce song.
♪ The world according to Chris is ♪
♪ Better to strike than get struck ♪
I had like all these backup dancers and I got to have this
Christina Aguilera, Britney Spears moment in the center
where I go like this and all the dancers are touching me.
It was just this really amazing, iconic moment.
- I think in this particular episode,
Kevin has kind of taken a bit of a directorial approach.
I get to sing a tiny, teeny bit.
But luckily, the other cast are like
the best singers in the world.
So, they sound amazing.
I don't get to sing too much in this one,
but there's no lack of Kevin Keller in this episode.
We'll just say that.
- Veronica right now is dealing with her parents.
They're obviously trying to sponsor the show,
and I think she's balancing that situation,
making sure that she's kind of still separating
her identity from who her parents are.
- At this point, we know that there has been a falling out
between Betty and Veronica, which has directly affected
Betty's relationship with Archie
and Jughead and Archie's relationship.
The two couples are going against each other in a sense.
And so going into this episode, they're still very strained.
Their friendship is definitely being tested
when they're put into this environment
where they kind of have to work together.
- They're not in a good place right now
and the musical kind of brings them together by the end.
- I mean, Betty and Archie playing Tommy and Sue,
I feel like, it doesn't stir the pot
as much as you think it would necessarily.
Which is nice.
I think it's very innocent.
It doesn't really hint at any
budding romance left between them.
It's more so just those are the roles that they play
and they kind of are awkwardly walking through them.
- Filming a musical episode is insane.
I think we're all running on fumes.
But it's amazing, and hopefully you get to watch some.
The cast is unbelievable, the choreography is insane,
the singing's amazing, the writing's great.
So, it's quite the production.
It's gonna be the biggest musical ever.
So, we're really excited.
- It can be tricky to pick it up with the little amount
of time we have and to put it with all the words
and the lines and all the cues and stuff.
So, it can be narly at times.
You're kind of taking everything as it goes.
I mean, I can sing a little bit,
but dancing isn't usually my thing.
Unless I'm at the club or something.
- KJ's an amazing dancer and he keeps making fun of himself
for doing it, but he's actually doing a very good job.
(laughs)
- I was in the ensemble a lot.
I didn't get too many leading roles
when I started out doing theater.
I played Veruca Salt in Willy Wonka.
And, actually, Camila did as well.
We bonded over that one of the first times we met.
I was in Annie.
I was in The Sound of Music.
I played one of the Von Trapp kids.
So, yeah, I feel like I'm well-versed
in just the musical theater world.
- I mean, my brother has done three Broadway shows
and I'm a big part of that community as well.
And I live in New York when I'm not here,
so I feel like all of my acting interests
have kind of compounded into this episode.
So, I'm personally very excited about it.
- I didn't do musical theater in college,
but I did a lot of it in high school.
So, now I'm like excited to be using all of those skills
that have been kind of just sitting there.
(laughs)
It's like fierce, sexy choreography
and that's kind of the stuff I lean towards.
This is the first time Veronica has worn jeans
and will ever wear jeans.
I don't think she'll ever wear jeans again.
I only wear skirts on the show, so I was happy
to wear something that I feel super comfortable in
that's like free and I can move.
Usually I'm in tight skirts where I'm like...
(laughs)
