It includes the return of David Howard Thornton and Samantha Scaffidi, who portrayed Art the Clown and Victoria Heyes, respectively, in the first film, and stars Lauren LaVera, Elliott Fullam, Sarah Voigt, Kailey Hyman, and Casey Hartnett.

The plot follows Art's resurrection and pursuit on Halloween night of teenage Sienna Shaw (LaVera), who discovers that she is destined to defeat him.

Leone secured finances from private investors prior to filming, and he launched an Indiegogo campaign with a $50,000 goal to produce a practical effects-driven scene.

One year later, teenager Sienna Shaw is preparing her Halloween costume: a Valkyrie character designed by her recently deceased father.

Sienna has a panic attack when her friends Allie and Brooke discuss Victoria Heyes's mutilation of talk show host Monica Brown.

Jonathan shows Sienna and their mother, Barbara, his father's sketchbook, filled with newspaper clippings revealing that the Little Pale Girl bears resemblance to Art's first victim Emily Crane.

At the Halloween party, Brooke spikes Sienna's drink with MDMA and she has a panic attack after seeing the Little Pale Girl in the crowd.

The Little Pale Girl imitates Jonathan pleading for a ride home, so while Sienna goes searching alone after a big argument on the way there, Art murders Jeff.

On February 12, 2019, Leone revealed in a post on his social media, showing the cover page, that the first draft of the screenplay was complete.

[11] Leone envisioned the concept of the film dating back to 2008—with an idea of an angel-warrior costumed heroine battling the Art the Clown character.

[13] During a lunch with Leone and David Howard Thornton, the actress who plays Sienna, Lauren LaVera, was told of this intended dynamic between her character and Art.

[13] Both Thornton and Scaffidi were confirmed to reprise their respective roles of Art the Clown and Victoria Heyes,[14] becoming the only returning cast members of the prior film, other than a brief voice cameo by Michael Leavy (who played Will the Exterminator in the original film) as the Club Announcer and DJ voice, and Corey Duval, who returns as the coroner from the first installment.

There were also reports of Steven Della Salla and Jason Leavy, the two cops in the original film, returning in cameo appearances as well; the three are all producers on the second installment.

On October 15, it was announced that Felissa Rose, Chris Jericho and Tamara Glynn had joined the cast in cameo roles.

[21] On September 7, Leone revealed that he was in the process of working on the prosthetic makeup for Victoria's disfigured face in preparation of filming Samantha Scaffidi's scenes.

The film has gained significant media coverage because of the gore effects, particularly for the notorious "Bedroom Scene," depicting the lengthy murder of the supporting character Allie (Casey Hartnett).

[34][35] While initially set for a one-week limited theatrical release, audience demand led Bloody Disgusting to announce that Terrifier 2 would remain in theaters for a second weekend on October 12, 2022.

Variety called the film's success a "shock" to the industry due to its low budget, limited mainstream marketing, and lack of marquee stars.

To see it snowballing, the word of mouth growing, people getting sick and fainting and it really taking off, I never expected this or for it to make millions of dollars in theaters.

The website's consensus reads: "Terrifier 2 outdoes the original in every way – which makes it bad news for the squeamish, but a bloody good time for genre enthusiasts.

"[48] Matt Donato of IGN while stating the film has "underdeveloped subplots and themes" noted it as an improvement of the original film and highlighted the performance of LaVera, writing that she "rules as Sienna in her angel-winged fantasy armor as a final girl fighting for family, facing her demons, and screaming bloody war cries in Art's mocking face.

[53] Adam Graham of The Detroit News rated the film a grade D, calling it "[a] bludgeoning exercise in splatter, which drags on well past the two hour mark with no sense of purpose other than its own inert attempts to shock.

"[54] Following its release, there were several reports of viewers vomiting and fainting during their screenings of Terrifier 2, with one instance allegedly having emergency services being called.

[55][56] Speaking on the audience reactions to the film, director Damien Leone remarked, "Listen, I would have loved to have a couple of walk-outs, I think that's sort of a badge of honor because it is an intense movie.

[61] In October 2022, Leone said he had an entire treatment for a third film but it "is getting so big that it could potentially split into a Part 4 because [he] wouldn't want to make another 2 hour 20 minute movie.

Leone, producer Phil Falcone, and actors David Howard Thornton and Lauren LaVera are all slated to reprise their roles.
