Horror fans now have a good selection of streaming options with genre-specific streamers like SreamBox and free services like Tubi, which has leaned heavily into the horror market. However, there's no better horror platform than Shudder. It's currently the largest horror streaming service, with over 1 million Shudder subscribers, and all Shudder content can now be watched on the new AMC+ streaming service as well.

One of the most popular subgenres in horror is animal horror, where giant beasts of all kinds stalk, hunt, and attack, proving that sometimes wild animals can be the scariest serial killers of all.

Boar (2017)

A giant boar drags a victim to her death

Boar is an Australian horror film that features a giant boar running wild in the Outback, killing everything and anyone it feels is threatening its territory. While the movie has a somewhat amateur feel - thanks to poor acting and sloppy pacing - it's still an absolute must-watch for fans of creature features. It's especially regarded for its use of practical effects, something that sadly isn't seen enough these days. Much like animal horror films from the past, Boar uses CGI for certain scenes but also uses a giant animatronic puppet for close-up scenes to create gory and visceral moments that really steal the show.

Monsterous (2020)

A giant Sasquatch lurks in the moonlight

Bigfoot is an interesting concept. As a cryptid, sasquatch lingers somewhere between an animal and the supernatural. However, as a living creature, bigfoot movies tend to play out just like animal horror. That is, except for Monsterous.

Whereas most bigfoot movies, like Exists, goes for full-blown killer bigfoot action, Monsterous interestingly shows that humans are the real monsters. The story centers around mystery, murder, and deceit, with bigfoot lurking quietly in the corners of the film, creating a lingering feeling of suspense and unknown danger. It's certainly a unique film, going for a slow-burn effect rather than bigfoot gore, but the unique take fared well with critics who praised the interesting take on bigfoot.

Fangs (1974)

The cheeky poster for Fangs reads "Biggest Bite Since Jaws"

Fangs is sure to please everyone who loves obscure oddities. Like some weird mix of John Waters and Snakes on a Plane, Fangs is a low-budget, ridiculous, yet insanely fun horror movie about a man who passes out deadly snakes to his enemies. The movie is also curiously sordid and perverse, using the snakes in a weirdly sensual way that only further builds the film's unsettling vibe. It's the kind of movie where none of it really makes sense... which only adds to its obtuse and tawdry charm.

Bad Moon (1996)

The werewolf in Bad Moon stands outside his house during a full moon

This Canadian film was initially bashed upon its theatrical release but has since gained more respect amongst audiences, and Bad Moon is now considered one of the best werewolf movies ever. Nowadays, the film is lauded for using a werewolf costume instead of attempting CGI.

While the costume created some degree of bulkiness and a lack of agility for the actor inside, both ended up coming off as somewhat disturbing to watch, as if the character was genuinely struggling with his new malformed body. Interestingly, the movie was based on the novel, Thor, which recounted the story from the perspective of the family dog.

Prey (2020)

The diseased and crazed dog in 'Prey' gets ready to bite

In a film that suddenly became extremely relevant during the COVID pandemic, Prey centers around a young paraplegic girl and her service dog. Unfortunately, after being bitten by an infected bat, the dog develops a strange disease that turns him murderous. Prey goes deeper than most horror films as well, as the main character starts off the movie being shrowd in self-hatred and even wishes to die. But as she comes closer to actual death, she realizes the power of living and becomes determined to fight like hell.

Monstrum (2018)

The giant monster in Monstrous attacks a Korean army

Within the Veritable Records of the Joseon Dynasty - the very real annual records kept in Korea from the 1300s-1800s - lies numerous stores of famine, war... and even monsters. In the year 1527, the records state that a strange creature stalked the royal palace. While it's unknown whether the monster was simply a rogue tiger or wolf or something else entirely. Monstrum went more for the monster element, creating a hulking sabertooth tiger-like creature deadset on carnage and mayhem. The movie builds on Korea's history of fascinating monster movies like The Host.

Uncaged / Prey (2020)

A lion stands in the middle of Amsterdam in 'Uncaged'

From famed Dutch director, Dick Maas, who shot to stardom in the 80s with his blockbuster skyscraper-set horror movie, De Lift, comes Uncaged (released as Prey in Europe). Like most of Maas' films, Uncaged is a campy, bloody romp about a man-eating lion who escapes and is now terrorizing the people of Amsterdam. The film is filled with lots of ridiculousness, tons of gore, and an endless array of fun and outlandish scenes, including one where the man-eating lion makes his way onto a tram car. For fans of guts, gore, and mayhem, it's an absolute must-watch.

Tammy and the T-Rex (1994)

A T-Rex with a human brain looks at himself in the mirror for the first time

Much like bigfoot, dinosaurs are hard to place. After all, they were real animals until their disastrous date with an asteroid. But any fan of giant animals causing havoc will love Tammy and the T-Rex. This cheeky and absurd movie stars Denise Richards and Paul Walker, whose brain has been inserted into a giant robotic T-Rex. Yes, Paul Walker stars as a giant. robotic. Tyrannosaurus-rex.

Tammy and the T-Rex is one of Shudder's funniest movies, and as long as viewers can get into the zany concept, it's tons of fun. Best of all, upon original release, the movie was gutted to appease the MPAA, ending up heavily neutered to receive a PG-13 rating. However, Shudder has the original, unrated, fully-uncut film, allowing viewers to fully absorb this gory, bonkers madcap of a movie.

Piranha (1978)

The namesake pirañas try to escape in the 70s classic

Pirhana is an oddball film that somehow spawned a franchise that's lasted for decades, with the most recent installment, Pirhana 3DD, being released in 2012 - more than thirty years after the original film. The movie centers around killer piranhas created by the US military that were meant to be used as bioweapons during the Vietnam War. However, they've now escaped into a river, killing everything in sight. Much like its newer counterparts, the original film is filled with slapstick comedy and social commentary, which makes the film walk a tightrope between horror and comedy. In the years since its release, Pirhana has become a bonafide cult classic.

Great White (2021)

A great white opens his jaws to attack a swimmer

No animal horror list would be complete without a shark film, and Shudder has the exclusive American streaming rights for Great White. In the Aussie film, a seaplane discovers an overturned yacht off the coast of Nothern Australia. In an attempt to help, the plane lands next to the yacht, only to discover that they're now being circled by hungry great white sharks. Though the film was met with mixed reviews, Great White is a sure bet for fans of shark movies and creature features, because genre fans can't seem to get enough of giant sharks stalking, hunting, and terrorizing unsuspecting victims. The movie was also made by the producers of 47 Meters Down.
