Ahead of the world premiere of

Hustlers

Madeline Brewer

(and more, but no spoilers here)—I sat down with the

Riverdale

star during TIFF to talk early-aught trends, all those vomit scenes, and what she and boyfriend Cole Sprouse are going to be for Halloween.

Ha! That jewelry that would turn your skin green or blue:

“It was just the best discount bodycon dresses money can get.”

Was there a look you just refuse to wear from that era?

“I refused to wear the hip-hugger jeans.”

The low-low-rise and muffin tops?

“It truly mortifies me that I wore those. Obviously I wore them in middle school. My mom sent me a picture of [myself] wearing those pants the other day, and they are literally like you’re about to see my vagina. It’s right on the cusp. And my mom goes, ‘Where is your crotch?’ She sent me that photo because there is like

space between the top of my jeans and my legs. I was like, ‘I truly don’t know. I couldn’t tell you.’ All I know is [I was] 13, so I clearly didn’t have any love-handles going on—nothing to grab on to, I was like a stick. So it worked at that point, but Mitchell made me try on a couple [pairs], and I was like, ‘No, don’t do it.’”

What about the bodycon dresses?

“I don’t wear bodycon dresses ever. So, no. I really don’t think I would want to wear anything that I wore in that movie in my life. Even walking from my trailer to set, to the bar where we were filming or the strip club, I felt so self-conscious about the way I looked because it was so over-the-top. I had blue eyeshadow on…horrifyingly blue eyeshadow. It felt so out of my comfort zone. It was kind of insane because I’m very minimal. Especially day-to-day, I don’t wear any makeup. So it was a whole other world to be glammed and dolled up so much every day and to have my boobs on display all the time. It was quite a different experience. I’m more conservative than that.”

Your character has a pretty adverse reaction to stress, but she’s made it so endearing. Was it hard to film all those vomit scenes?

“People [would ask], ‘Are you nervous?’ I don’t think I was. It was more so like, here goes nothing! I don’t know what to expect. I’ve never had to do this before. I mean it was funny, I think Lorene said ‘Poor Annabelle’ like, eight thousand times while we were filming.”

Seriously, poor Annabelle!

“She’s so young and sweet. It’s such a genius way of reminding the audience that she’s so young. Instead of being like, oh yeah, she’s the baby of the group, or she’s new to this, or she got pulled into this. That story is told by her vomiting because she’s just overwhelmed. I don’t have that reaction when I’m overwhelmed, but I can appreciate the people who do and how unfortunate it is. It was definitely an experience.”

What is fake vomit made out of?

“Well, it’s different for every scenario. People come up with all kinds of things. Mine was best-case scenario. It was crushed animal crackers and sprite. It tasted like leftover animal crackers in my mouth. It was fine. Mushy food really grosses me out, so that was my biggest fear, having to put that in my mouth…like actually making me want to throw up from putting that in my mouth. But it was fine.”

What day on set sticks out in your mind?

“Will Ferrell came to visit us, and I literally avoided him because I was so starstruck. I was like, ‘I don’t want to meet him. I’m nervous, I don’t want to.’ He’s one of the producers of the movie, so he came to visit one day [when] we were shooting at the club, and I literally avoided him because I was scared.”

What was it like dancing beside J-Lo?

“Look, clearly I’m not good at dancing or trying to look good. [I] was just trying to have fun, like how you would drunkenly dance with your friends. So it’s more so like,

God, please don’t watch that and think I’m trying to look good dancing.

It was fun in the moment, and it was a really cool and special experience.”

I heard you’re pretty good at special-effects makeup. What are you going to be for Halloween?

“I am! Oh my god, I haven’t done that in a really long time, actually. I kind of went from special-effects makeup to face painting. So I’ve done a lot in the past. Now I don’t really have the time, which sounds so stupid, but I really don’t. It takes a lot of time to do those things. I think I’m leaning in towards a character for Halloween. I think I’m going to do it with my boyfriend, Cole. I don’t want to spoil it if it’s not going to happen, but it’s a TV duo.”

That’s a good little teaser:

“No special effects this year, but maybe a wig.”
