Slasher

Premise

Each season is centered on a masked killer with an unknown motive for killing their victims. The first season, retroactively subtitled The Executioner, was co-produced by Chiller and Super Channel, and centered on a mysterious figure billed as the Executioner who terrorizes the fictional town of Waterbury, Canada. The second season, subtitled Guilty Party, follows a group of former summer camp counselors who return to their isolated campground in order to retrieve the body of a murder they committed, before being targeted, one by one, by an unknown killer. The third season, Solstice, is centered on a group of neighbors who are targeted during the summer solstice period due to their complicity in not saving a murder victim who was killed one year earlier in front of their apartment complex by the same killer, nicknamed the Druid. The fourth season, Flesh & Blood focuses on the wealthy yet dysfunctional Galloway family, but after the sudden death of the family's patriarch, the remaining family members are forced to compete in a series of twisted games in order to win the family's entire fortune, all the while being hunted by a masked killer called the Gentleman. The fifth season, Ripper takes place in 19th century Toronto, where a group of rich elites are hunted down by a serial killer wearing widow's weeds, coincidentally named the Widow.

Guilty Party (2017)

In the dead of winter, a group of former summer camp counselors return to the resort where they participated in the murder of Talvinder Gill, then hid her body. The body has vanished from its secret hiding spot. They are then trapped in the resort and, one by one, killed by a murderer in a parka.

Solstice (2019)

Kit Jennings, a sex and drug addict, is murdered by someone using a "Druid" costume in front of an apartment complex during the summer solstice and the neighbors don't help him.

Flesh & Blood (2021)

Slasher: Flesh & Blood follows a wealthy but dysfunctional family gathering for a reunion on a secluded island. Their old wounds and competitive rivalries flare up when the family realizes a masked killer is on the island, intent on cruelly picking them off one by one.

Ripper (2023)

Slasher: Ripper takes place in 1904 (with flashbacks to 1892) – where there is a killer stalking the streets, but instead of targeting the poor and downtrodden like Jack the Ripper, the Widow is meting out justice against the rich and powerful.

Production

Development

Slasher was created by Aaron Martin, who was inspired after his work on the first season of the medical series Saving Hope, specifically his writing of two episodes in which "people got chopped up." He wrote the first episode of the series as a spec script, aiming to offer it to prospective studios and show a writing style that was different from his previous work (e.g. Saving Hope, Degrassi: The Next Generation, and Being Erica). Though the script did not receive immediate interest, Shaftesbury Films optioned it in late 2014 with an eight-episode order and started pitching around to networks. Canadian premium network Super Channel ordered the project after showing interest in Slasher's fixed-end format. The now-defunct American network Chiller, which specializes in the horror thriller genre, joined production shortly after; Slasher became Chiller's first and only foray into original scripted series content.

In May 2017, Shaftesbury Films confirmed that the series would not return to Super Channel or Chiller for a second season. However, streaming service Netflix acquired the rights to the second season. The second season was released via Netflix on October 17, 2017.

In August 2018, it was announced that production commenced for the third season of Slasher. On October 23, 2018, Adam MacDonald was announced as the third season's director. On April 24, 2019, it was announced that Aaron Martin had stepped down as the showrunner and Ian Carpenter would serve as the primary showrunner and one of executive producers of the third season.

On November 12, 2020, the series was moved to Shudder for a fourth season. On February 10, 2022, Shudder renewed the series for a fifth and final season.

Writing

Slasher employs a season-long anthology format, with an overarching mystery storyline that will be resolved upon the season's conclusion. Series creator Aaron Martin was inspired by the format of American Horror Story, stating in 2016 that prospective subsequent seasons would retain the American Horror Story style of self-contained storylines; they would be used along with ideally as many actors from previous seasons as possible in new roles.

Martin has aimed to tell "a modern-day monster story" in Slasher, combining three of his favorite genres: the contemporary murder mystery (à la Broadchurch), the works of Agatha Christie, one of Martin's favorite crime writers, and the classic slasher films which he grew up with. In terms of the latter, Martin has specifically cited the influences of Halloween and It Follows in Slasher's use of a mysterious singular embodiment that is responsible for a series of killings. Not wanting to have the show's killer be "a mythological creature" (as he feels the killers in most slasher films do not have much mystery surrounding them), Martin also uses elements of the traditional whodunit in Slasher: the characters, many of whom have mysterious backgrounds and their own reasons for possibly being the killer are featured, explored, and eliminated from consideration, one by one either through death or the natural deductive process, until the "all too human" killer and their motivations are revealed.

Filming

Production on Slasher's 8-episode first season was announced on July 28, 2015, with filming taking place between then and October 2015. Three Northern Ontario municipalities — the cities of Sudbury and Sault Ste. Marie and the town of Parry Sound — would stand in for the show's fictitious location, the town of Waterbury. Unlike most television series that film their episodes in order, under the direction of Craig David Wallace, the series was shot as if it were a "super-sized" movie. Scenes from multiple episodes were filmed simultaneously, with the availability of locations and cast being factored in. The out-of-order schedule allowed the actors to acknowledge their characters' fates, especially those who had to film their death scenes one day but return later to film earlier scenes if necessary. As an example, Martin cited Mark Ghanimé's first day on set, when his character, Justin Faysal, was laid out in a casket for a scene early in Slasher's third episode. Justin's death, which took place in the second episode, would be filmed later on.

On May 1, 2017, Slasher began filming a second season in Orangeville, Ontario, Canada.

Release

A first trailer for the series premiered on November 26, 2015. On May 25, 2016, the entire first season of Slasher became available to stream instantly on Netflix US. On October 17, 2017, the full second season of Slasher became available to stream on Netflix in various countries. The series airs in the United Kingdom on Pick, where the first season premiered on May 10, 2016 and the second season on May 1, 2018. On May 23, 2019, the full third season of Slasher became available to stream in various countries on Netflix. In April 2020, Netflix removed all three seasons of Slasher with no explanation or prior warning. In late June 2020, all three seasons of Slasher were re-added to Netflix.

Reception

Critical response

Slasher has received positive reviews. For the first season, the review aggregator website Rotten Tomatoes reported an 80% approval rating with an average rating of 5/10 based on 5 reviews. Zap2it called the series "a whole lot of fun" and "something for everyone," praising the series' anthology nature, its cast of characters, storyline, plot twists, bloody violence, and even the series-within-the-series Falcon Husbandry (shown as a favorite of Robin and Justin's in Episode 2). Bloody Disgusting awarded the show four skulls out of five, praising Katie McGrath as a great "protagonist and possible final girl" and the series' decision to feature an adult cast, rather than teenagers, with well-developed characters and a "decidedly classic" presentation. On the occasion of Slasher's Super Channel premiere, The Globe and Mail's John Doyle, while remarking that it "is no masterpiece of horror, nor was it meant to be," called the show "very well-crafted," praising its "exceptional cast" and tight pacing, and noting fans of gory horror will appreciate its bloody scenes.

Spin-off

A sixth season of Slasher entered production under Aaron Martin at Shudder before being rebranded as a spin-off miniseries set in the same universe, Hell Motel, which premiered on June 17, 2025. In 2026, Hell Motel was renewed by Shudder for a second season in lieu of any further seasons of Slasher, titled Hell Motel: Murder at Red Mountain. As of July 2026, filming has completed.

In Season Two, Hell Motel: Murder at Red Mountain, Set at a mountain resort known for eliminating people’s inhibitions and amplifying their desires, the new season continues to reveal the chilling consequences of surrendering to our darkest impulses amidst the unique Cold River landscape.
