[1] In 1944, during World War II in Ukraine, the remnants of the 5th SS Panzer Division Wiking are fleeing from the Red Army.

At the local hospital, the medical student Sebastian finds some pills which Beckert has been using to treat a comatose patient.

Rather than getting high, he starts to develop acute hearing and improved vision, is able to talk to dogs and tormented by extreme thirst.

John puts the remainder in a bowl of punch to liven up the party, unwittingly infecting multiple guest including Vega.

Ander Banke and Magnus Paulsson had been trying to make a Swedish horror film for years but with little success, until a script by Daniel Ojanlatva was sent to them about vampires showing up in Norrland.

Grete Havensköld, who had starred in Astrid Lindgren films as a child, was cast as Annika's daughter Saga.

Per Löfberg had been in the hit romcom Ha ett underbart liv and in the cult film Evil Ed and was cast in a then-secret role, and Carl-Åke Eriksson had played small parts in several films and television series was cast as the professor.

The hideous supervampire that appears at the end was played by actor Kristian Pehrsson wearing a full body suit.

Other than the score the soundtrack is mostly made up of Swedish pop- and rock-music, among those Millencolin, Luleå hardcore punk band Raised Fist, Langhorns, Quit Your Dayjob, Son Kite and then newcomers BWO.

According to the producers, and to director Anders Banke, Frostbiten became the first horror movie ever to be screened in North Korea.

[9] The movie was a big hit in Russia and launched Anders Banke's career in the Russian film industry.

[citation needed] After Cannes, Frostbiten was by far the most popular Swedish movie on the foreign markets that year.

[14] A reviewer for the site Film Threat wrote, "Ever since Buffy the Vampire Slayer and Scream infiltrated the fear-film genre, something's been rotten in Transylvania.

Playing horror for winking insider references and juvenile giggles, any real juice has been extracted from the cutting-edge school of cinema that spawned Re-Animator, Dead Alive, and Evil Dead, three brilliant examples of horror that combined ferocious splatter with truly inspired humor.

The reviewer also pointed out that the setting was perfect and commented that the Swedish landscapes provided a wonderful backdrop for the movie's dark subject matter and that it looked beautiful in a very gruesome kind of way.

[19] The horror site Eatmybrains.com gave it 4/5 stars and comments: "Banke’s film exhibits a laid back, droll sensibility perfectly in keeping with its national temperament, and has a unique deadpan sense of the comedic that perfectly complements the material without cheapening it".

The title is an obvious play on frostbite, because the movie takes place in a frozen environment and features vampires who bite people.

He describes the teen vampires as a more sadistic and brutal breed of the undead, an anarchist and aggressive pack straight out of The Lost Boys.

He lays weight on the fact that, while following traditional vampire mythology closely, the film puts it into context with modern Sweden.

He argues that if the film had been made in a more religious country, the priest would have been a main character, who would have provided information about the vampires and lead the fight against them.

[24] Sarah Clyne Sundberg of Sweden.se suggested that the film possibly reflected unprocessed Swedish war guilt.

[25] She also mentioned that the film had some great visual and verbal puns and described it as good old-fashioned gore fest.

Film4 read the film in a similar way, stating: (B)uried somewhere amidst the monstrous transformations and belly laughs is an uncomfortable critique of Sweden's much-vaunted wartime neutrality, and her current anxieties about immigration.

For this is the tale of a Nazi soldier finding refuge in Sweden with surprising ease, and continuing unchecked in a eugenics programme of his own (with bloodsuckers as the new master race) - and the locals either fail to notice what's happening in their midst or else fall in line with alarming gusto.
