Netflix is set to release a new horror series called Something Very Bad Is Going to Happen, and it’s already gaining attention for its eerie storyline and strong creative team. Created by Haley Z. Boston, best known for her work on Cabinet of Curiosities and Brand New Cherry Flavor, this upcoming series promises a haunting mix of psychological horror and slow-burning suspense.
Produced by the Duffer Brothers (creators of Stranger Things) through their production company Upside Down Pictures, the show is expected to deliver the same kind of atmospheric tension and character-driven drama fans have come to love. At NetFilming, we’re here to give you all the details about where this chilling series was filmed.
What is Something Very Bad Is Going to Happen About?
The story is about a young couple getting ready for their wedding. A joyful party quickly turns into something scary. This slow-building horror narrative takes place over a week and goes deep into relationships, secrets, and psychological anxiety. It starts with a wedding week and ends with something absolutely awful.
The main cast includes Camila Morrone as the bride and Adam DiMarco as the groom. The ensemble is rounded out by a strong lineup: Jennifer Jason Leigh, Ted Levine, Gus Birney, Jeff Wilbusch, Karla Crome and Zlatko Burić. With such a solid cast and a horror-proven writing team, expectations are high.
Something Very Bad Is Going to Happen Filming Location
The primary filming location for Something Very Bad Is Going to Happen was Mississauga, Ontario, Canada—using Mississauga’s calm suburban and indoor spaces (banquet halls, homes, etc.) to contrast the building dread
Mississauga, Ontario, Canada
The majority of Something Very Bad Is Going to Happen was filmed in Mississauga, a city located just west of Toronto, in Ontario, Canada. This region has become a favorite filming spot due to its blend of urban and suburban locations, which work well for both domestic and international productions.
Mississauga’s peaceful homes, quiet streets, and banquet facilities made the perfect setting for a horror series about weddings. The peacefulness of the city and the horrible things happening on television make the stress even worse. Most likely, wedding scenes were filmed in private homes, rented locations, and maybe even outside places that might easily be made into scary scenarios.
Toronto, Ontario, Canada
Filming took place in sections of Toronto as well as Mississauga. Toronto is a popular place for big movies and TV shows to film because it has bigger studios, more flexible urban settings, and a robust production infrastructure. Some internal shots or scenes of the city that set a mood were probably shot here to give the show a greater diversity of visual styles.
Together, these two Ontario locations gave the filmmakers a diverse range of settings to bring this psychological horror story to life.
When Was the Series Filmed?
Production on Something Very Bad Is Going to Happen began around January 20, 2025, and wrapped up by April 11, 2025. Some sources say that filming went on until late April or early May to get the last scenes or do reshoots.
The fact that the episode was filmed during Canada’s harsh winter and early spring may have naturally made the sights creepy. The streets are blanketed in snow, the skies are overcast, and the nights are longer, which makes for a naturally creepy ambiance that is great for a horror show.
Who’s Behind the Camera?
Haley Z. Boston is the creator and showrunner of this new Netflix original. She has a distinct way of delivering stories. Several talented directors are working with her, including:
- Weronika Tofilska (Baby Reindeer)
- Axelle Carolyn (The Haunting of Bly Manor)
- Lisa Brühlmann (Killing Eve)
Each director brings a different creative touch, but all stay true to the chilling tone and layered psychological horror Boston is known for.
The show is being produced under Upside Down Pictures, with support from Hilary Leavitt and Andrea Sperling, who are both experienced in producing high-quality TV dramas.
Something Very Bad Is Going to Happen Behind The Scenes
The atmosphere on set was intense yet collaborative, with cast and crew bringing their all to this chilling wedding-week story. Camila Morrone, who plays the bride, shared her excitement on Instagram:
“ITS OFFICIAL! Something Very Good Is Going To Happen. The creatives behind this are A++ genius.… I cannot wait for what we’re about to make. See you at the altar, I hope…”
Her enthusiasm reflects the energy behind the cameras—everyone was deeply invested in delivering a resonant and eerie performance.
Haley Z. Boston, the creator and showrunner, set the tone and worked closely with filmmakers like Weronika Tofilska, who was just nominated for an Emmy for Baby Reindeer. Boston wanted the terror to be realistic, so she focused on how a “perfect” moment slowly turned into tension and fear. Reports say she appreciated Ontario’s blend of peaceful residences and wide-open spaces for complementing the mood of the event. This shows how tranquil suburban areas may make psychological anxiety worse.
On set, Camila emphasized how much working here felt like a shared journey:
“There’s just so much experience that comes with being on set and working with good actors, and having bad days and good days.”
Her words capture the emotional journey of filming—moments of doubt, breakthroughs, and communal support. Early spring weather in Mississauga added to the cold, moody atmosphere, while director Tofilska and camera teams experimented with long, lingering shots to create an unsettling intimacy during wedding scenes. Each creative choice served the aim: to make domestic familiarity feel eerie and trust between characters fray in the shadows of celebration.
