In Monster Party, friends Casper, Dodge, and Iris are thieves — and, they’re pretty darn good ones. They’ve been pulling small-time heists, earning enough money to get by, at least. But the stakes are raised when a gambling addiction puts Casper’s dad in a bad spot with the wrong people, and Casper needs the money to bail him out.

The trio decides to pull their biggest job yet to get the funds. The target? An ultra-rich family throwing a dinner party. The goal? All the cash they can grab from the safe while everyone is distracted. Things soon go wrong, however, when Dodge discovers the family’s dark secret — they’re all killers, and this is no regular dinner party at all, it’s a Monster Party.

ScreenPicks spoke with Lance Reddick (from TV shows Fringe and Bosch, and the John Wick films) about playing the king of the killers, Milo.

ScreenPicks: Have you seen the finished film yet? It’s pretty wild.

Reddick: Yes, I thought it was great. I wasn’t sure how it was going to turn out because we shot it so fast and stumbled in the beginning in the process but yeah … and as far as it being ‘wild,’ yeah, it is!

ScreenPicks: What made the process so bumpy?

Reddick: Well, only in the beginning. I think it was Chris [von Hoffmann’s] first major film. He’s done one film before this. But, the producers were really great.

ScreenPicks: What drew you to the project itself?

Reddick: It was the script and the character.

ScreenPicks: Speaking of your character, Milo, how did you approach playing him — the benevolent patriarch of a dysfunctional family or, as Julian McMahon’s character asserts, cult leader?

Reddick: It depends on who you talk to. If you talk to Milo, he’s a patriarch. If you talk to Julian — cult leader. Now if you’re asking me, Lance, as a viewer who’s watching the movie and not as the character? Yeah, he’s a friggen cult leader! It’s a cult! It’s crazy. He’s an egomaniac. His ego is off the charts. He thinks that he can control everything. He thinks that he can control himself. You have a room full of serial killers and … you think you can make them not want to commit murder? That’s an ego.

ScreenPicks: You have a very violent, explosive scene in the film. Where do you go to find that energy, that rage?

Reddick: [Laughs] That’s a tricky question to answer because I’m not sure that I want to go into all of my pathologies. But, tapping into rage, for me, rage is kind of underlying for the character. Everyone has their thing — these serial killers. With the teens, it’s like a cat playing with a mouse. With my character, I think that it’s significant that in both of his explosive moments, it was with striking someone. So, the way I look at him psychologically is that he gets his joy with killing people, when he was a serial killer, it was to do it with blunt force trauma. Even the fact that he carries that cane around … because he’s not decrepit! He doesn’t need the cane. It’s an ornamental piece, but I also feel like it’s a tactile thing. He’s very kinesthetic, very physical.

ScreenPicks: You get pretty bloody in this movie. Was that all practical effects, the gore in the film? 

Reddick: For my scene, it was all practical effects. They did blood on me and they had a mat there that I was pounding on. For other parts of this film, I honestly can’t say. But for my stuff, practical. They had to put a [piece] on to [one of the actors] so I could rip that off of him. [Laughs]

ScreenPicks: There are a lot of young-ish actors in this film. Is there anyone you enjoyed working with in particular or who stood out to you?

Reddick: So many of them are already … like Brandon  [Michael Hall] was already cast as a lead in that “Mayor” show. It didn’t do well but he’s already a lead in another series! Erin [Moriarty] was already a rising star. I was a huge fan of her from her turn on first season of “Jessica Jones.” I didn’t know who she was when I saw the show, I was like, “Who is this actor?” And when I met her, I was like, “I know this girl. I know this girl. How do I know her face?” Because she was so kind of pitiful and washed out as that character and she is so stunning in real life. And she’s a real actor’s actor. And Kian [Lawley] … it was one of those things where I didn’t know what to expect because his background is more as a YouTuber than an actor. But when I saw the movie, I was like, “God damn!” He killed it — no pun intended. He’s fantastic.

ScreenPicks: On the flipside, how was it working with seasoned actors Julian McMahon and Robin Tunney?

Reddick: I never worked with Robin before. I only knew her through her work and her reputation. And she is a hoot! She is such a pro and she does doesn’t suffer fools gladly. [Laughs] And Julian is kind of a dominant personality and he’s a director … I’ve been a big fan of his for years. I mean, ever since “Charmed,” if you can believe that. Not that I was a huge fan and would watch “Charmed” a lot. It was one of those things that because I was a “Buffy” fan, it would be the next thing on, and I would keep watching it a little bit. And every time he would come on I’d think, “He’s really got presence! Wow!” So for me, I came into it being such a big fan, so I was really thrilled to work with him. Seeing how the movie turned out, I feel like we had really good chemistry. I would love to work with him again.

Monster Party opens in theaters November 2nd.
