Unholy Night: Zombie Grandma Christmas Horror Gets Shudder Trailer and Release Date

Unholy Night Gets Its Shudder Trailer and Release Date

Christmas Eve is supposed to be about family, food and tradition, and Unholy Night asks what happens when the family refuses to stay dead.

Shudder has released the official trailer and poster for the holiday horror comedy, and Unholy Night will begin streaming exclusively on Shudder on 4 December 2026.

The trailer and poster were reported on 9 November 2026.

The film is a Shudder Original and the feature directorial debut of writer-director Michael Gabriele.

It had its world premiere at the Fantasia International Film Festival earlier this year, where audiences voted it the best Canadian feature.

With festival buzz, a confirmed date and a seasonal hook, it is already one of the more intriguing titles in Shudder's Christmas horror line-up.

What Is Unholy Night About?

The story follows Gino, whose traditional Italian family Christmas Eve celebration descends into chaos.

The cause is a visitor nobody invited.

His long-dead grandmother returns from the grave and goes on a killing spree.

She is not alone.

As the night goes on, more of Gino's dead relatives start turning up around the neighbourhood.

Gino also reunites with his ex-girlfriend, Rene, and the two of them have to dodge the returning relatives while looking for a way to get rid of the whole family.

Their goal is simple.

They have to survive until the end of Christmas Eve.

The premise plays on a familiar fear.

Most people have dreaded a difficult family gathering at some point, and Unholy Night takes that dread literally.

Shudder describes the night as a bloody battle for survival.

The film is unrated and runs for around 91 minutes, according to listings.

Who Stars in Unholy Night?

Marc Bendavid plays Gino.

Bendavid is known for Dark Matter and Reacher.

Shailene Garnett, whose credits include Fire Country and Diggstown, plays Gino's ex, Rene.

The supporting cast includes Jacqueline Robbins, Al Sapienza, Ron Lea, Cristina Rosato, Ellen David, Toni Ellwand and Joe Pingue.

In a story built around a large Italian family sitting down to Christmas Eve dinner, a strong ensemble matters.

The living relatives have to feel like a real family before the dead arrive to tear it apart.

Michael Gabriele Makes His Feature Debut

Michael Gabriele wrote and directs Unholy Night, his first feature as a director.

Jef Burnham is also credited as co-writer.

Gabriele was already known on the festival circuit.

His short film Get Away won the Gold Audience Award for Best International Short at Fantasia in 2023.

Three years later, he has returned to the same festival with his first feature and won another audience prize.

That is a strong record with the audience that matters most to a genre film.

It also suggests Gabriele understands how to play to a crowd, which is a useful skill for a horror comedy.

A Fantasia Premiere and an Audience Award

Unholy Night had its world premiere at the 30th Fantasia International Film Festival, which ran from 16 July to 2 August 2026.

When the festival announced its Audience Awards, Unholy Night won the Gold Award for Best Canadian Feature.

The silver went to Louise Weard's Castration Movie Chapter III, while Angus Silver's Insectasy and Gloria Mercer's A Safe Distance shared the bronze.

Audience awards reflect how a film plays with a live crowd, which suits a horror comedy that depends on shared reactions.

The film is a Canadian production, and Fantasia is based in Montreal.

What Did Critics Say After the Fantasia Premiere?

Reviews from the festival have been mixed, and critics disagree about which half of the horror comedy works best.

Dread Central praised the film as both tender and gnarly.

Its review said the film separates itself from the many Evil Dead-style imitators with a more emotional approach.

The same review noted that it is not the pure exploitation gore fest the synopsis might suggest, and that its technical polish is serviceable rather than standout.

Pop Heist called it a fun dose of holiday hell and said it delivers Christmas horror done right.

Bloody Disgusting was less impressed and gave the film 2 out of 5 skulls.

Its review liked the violent opening and the emotional exchanges between the living and the dead.

However, it felt the film loses its way with the rules governing its returned dead, and that the second half becomes repetitive.

Horror Movie Blog also found fun kills and creative ambition, but felt the comedy is underdeveloped and the tone leans more serious.

The overall picture is a film with heart and some memorable violence, but with questions over its tone and its lore.

Where critics differ, the Fantasia audience clearly sided with the film.

A Christmas Horror Film With an Italian Perspective

One of the more distinctive ideas in Unholy Night is its cultural setting.

Bloody Disgusting's review notes that the film tells its story through an Italian perspective.

It describes the returning dead as ritornati, a zombie-like version of deceased relatives who come back to the family.

That gives the horror a family and cultural backstory rather than presenting the dead as anonymous monsters.

It also helps explain why the review singles out the exchanges between the living and the dead as the film's strongest moments.

Those scenes carry the emotional weight of the story, because the threat is someone Gino knew.

Unholy Night also joins a long line of seasonal horror titles.

One reviewer set it beside favourites such as Silent Night, Deadly Night and Krampus, which sit on many Christmas horror watchlists.

For viewers who feel there is not enough Christmas horror, that is a welcome addition.

When Is Unholy Night Coming to Shudder?

Unholy Night premieres exclusively on Shudder on Friday 4 December 2026.

The date appears in Shudder's November and December Season of Screams line-up.

That programme, a four-month celebration of horror, continues through the rest of 2026 rather than ending at Halloween.

Unholy Night is listed as a Shudder Original Film.

Listings give the film a runtime of around 91 minutes.

The coverage reviewed does not confirm availability in every territory.

UK viewers should check Shudder's listings closer to the date for exact timing.

What Else Is Landing on Shudder This Christmas?

Unholy Night is not the only seasonal horror arriving on Shudder.

Joe Bob Conquers Christmas, a hosted special with Joe Bob Briggs and Darcy the Mail Girl, airs live on Shudder TV on 4 December, the same day as the film.

It then streams on demand from 6 December.

The Shudder Original Red Snow follows on 11 December, centred on a 16-year-old Finnish teenager who dreams of a glittering vampire prince.

Before that, both versions of Black Christmas, the 1974 original and the 2006 remake, join Shudder's library on 26 November.

Viewers will also have a theatrical option on 4 December, when Universal's Violent Night 2 opens in cinemas with Tommy Wirkola returning to direct.

For horror fans, 4 December therefore offers two very different versions of Christmas carnage.

Is Unholy Night Worth Waiting For?

That depends on what viewers want from a Christmas horror film.

Anyone looking for a relentless splatter comedy may find the film more emotional than expected, according to some reviews.

Viewers who like their holiday horror with a family drama at its centre may see that approach as a strength.

The most consistent criticism concerns the film's rules for its returning dead and its pacing in the second half.

Those complaints come from a handful of festival reviews, and more opinions will arrive once the film reaches a wider audience.

What is clear is that Unholy Night arrives with a distinctive premise, a specific cultural setting and an audience award behind it.

For a horror fan building a December watchlist, that is enough to earn it a place on the list.

The Dead Are Coming for Christmas Dinner

Unholy Night takes a joke every family knows, that relatives can be hard to survive, and turns it into a bloody fight for the night.

Gino has to protect the people he loves from a grandmother he thought was long gone, while the rest of the dead arrive at the door.

The cast is led by Marc Bendavid and Shailene Garnett.

The film also marks a first feature for a director who has already won over Fantasia audiences once before.

There is still plenty to discover, including how the film handles its rules for the returned dead and how its mix of comedy and tenderness plays outside a festival crowd.

Unholy Night is a Shudder Original horror comedy from debut director Michael Gabriele, starring Marc Bendavid and Shailene Garnett. It won the Gold Audience Award for Best Canadian Feature at Fantasia 2026 and begins streaming on Shudder on 4 December 2026.
