io9 recently attended a special screening of A24s Death of a Unicornstarring Jenna Ortega (Wednesday) and Paul Rudd (Avengers: Endgame); they play a daughter and her father who accidentally run over a unicorn. And yeah, that seems about the sort of a film A24 would push for its cinema addicts. After the film director Alex Scharfman led a Q&A with Ortega and other members of the cast (minus Rudd) about the dark modern fantasy comedy. Death of a Unicorn offers an art-house take on the same concept explored in Cabin in the Woods; it pits the destructive nature of a unicorn against some deeply unserious rich peopleand a normie single dad (Rudd) trying to do his best for his daughter (Ortega) who unwittingly forges a bond with the unicorn they hit. Ortega shared her biggest challenge was keeping a straight face while her co-starswhich also include Tea Leoni, Richard E. Grant, Will Poulter, and Anthony Carrigansaid and did the most ridiculous things as their characters extracted the unicorns powers. I mean this in the kindest way possible: I could not trust anyone on this set. I couldnt make eye contact with anybody. I didnt want to look at certain people, she shared with the audience. Theres a bit where Anthony walks by, and hes talking about, this isnt the best use of timewalking by using a clock as a barrier. And theres not one take where I look in that direction. Ortegas Ridley is definitely the films moral core and audiences avatar, and the actor recalled enduring comedic torture to defend the unicorn. Theres so many moments Paul was really playful [on set] that way, [and would] add little things. I think its strange, because Im supposed to be kind of the most serious one in the film. Telling everyone why this is wrong, and nobody listens to me until the third act, she said. For me, it was definitely one of the more difficult jobs where I couldnt break. I was supposed to be, like, on the verge of tears. It was brutal. It was talking to brick wall after brick wall after brick wall. Like, every day, it was just, like, more and more intense, like, more of a throat vein or a forehead vein trying to express to people why this was wrong. Yeah, it was terrible.Ortega continued to describe her experiences on-set. Working with Paul, obviously, I was such a fan of his work previously, but also just such a sweet, normal, kind man, she said. Fully joking, she added, He was fucking hell. [Hes not here so] I can acknowledge the fact that hes a dick. That good-natured rapport helped build the relationship between their characters. Truly, though, [he was] so easy to form chemistry with. Yeah, likehes great, so easy to work with, [and] so much fun. [He] made the energy lighter, and I think because I didnt get to have [comedic fun]I had plenty of fun on this [finding] that balance and not bearing into the territory thats not yours, and make sure that everybody is in every right place. And it was a little bit hard with Paul [to not break], but hes just so supportive and just incredible to work with. Death of a Unicorn opens March 28. Want more io9 news?
