Rose Da Silva
The Hero of the film, Rose Da Silva goes to Silent Hill to solve what her daughter's connection to the doomed town is. She turned from a helpless woman to an Action Mom during the course of the film, willing to do anything to retrieve her daughter when she disappears, even making a questionable Deal with the Devil.
- Action Mom: She is Sharon's adoptive mother, and by the end of the movie, has few qualms with stabbing a cult member that posed a threat to her daughter.
- Anti-Hero: Considering she was willing to let Alessa rip apart the cultists, she's at least a Type III.
- Catchphrase: "SHARON!"
- Distaff Counterpart / Gender Flip: The film was originally meant to feature the game's hero Harry Mason, but the director changed him to Rose due to Harry apparently being very feminine due to being afraid of the monsters and being concerned for his daughter.
- Fright Deathtrap: Rose and Sharon are nearly killed in their SUV when Dark Alessa walks into the road.
- Knight Templar Parent: Rose is willing to help Alessa butcher the Cult members if it means getting Sharon back.
- Mama Bear: She has no tolerance for any threats on Sharon's life.
- Took a Level in Badass: Perhaps justified, given that she spends most of the movie handcuffed or unarmed. Until the climax in the church, that is, when she helps Alessa invade the church and even kills a cult member herself.
Christopher Da Silva
Rose's husband who is left behind when his wife and daughter run off to Silent Hill, and spends most of the film playing Sherlock trying to track down Sharon's origins and learns of her connection to Alessa Gillespie. He appears in the film's sequel, under the alias of Harry Mason.
- Henpecked Husband: Rose seems a bit dominating over him.
A highway patrol cop from Brahams, Cybil pursues Rose and Sharon after realising they're heading to Silent Hill and ends up trapped in the foggy town with them, becoming Rose's Lancer. She sacrifices herself to the Cult to save Rose and is burnt to death.
- Heroic Sacrifice: Cybil sacrifices herself to the Cult to allow Rose to reach Alessa. She is later burnt to death by the cult.
- Reasonable Authority Figure: Unfortunately, the people of Silent Hill don't respect her authority.
Alessa's mother, Dahlia was convinced by Christabella to "purify" her daughter, leading to Alessa's burning. Dahlia is banished from the Cult after realising the error of her ways, now wandering Silent Hill as the only citizen to be unharmed by Alessa's monsters, and becomes quite frantic when Rose, Cybil and Sharon appear in town.
- Abusive Parent: She doesn't mean to be.
- Adaptational Heroism: She's not a villain like she was in the game.
- Cassandra Truth: She tries to warn Rose about the cult and Alessa, but fails.
- Mama Bear: Her action to protect Sharon (whom she believes is Alessa) from The Brethren does count.
- Redemption Quest: She essentially wants to get this, and achieves it by the end of the film.
- What Have I Done: Has this reaction after she sees what Christabella did to Alessa.
- White Sheep: She's the only member of her generation who isn't a murderous fanatic.
- Wild Hair: Somebody get her a comb.
Officer Thomas Gucci
A police officer who has a connection to Silent Hill, having rescued Alessa from the fire, who later escaped Silent Hill before Alessa turned it into hell. He accompanies Christopher to Silent Hill to look for Rose and Sharon.
- The Reveal: Officer Gucci is revealed to be the one who saved Alessa from her burning.
A citizen of Silent Hill, Anna was born and raised on the Cult's lies and knows very little about the outside world or the town's own history, let alone the crimes the Cult performed on Alessa. Due to her upbringing, she possesses a very childlike demeanour. She hangs around with Rose and Cybil for a while, before being ripped apart by Pyramid Head outside the Cult's chapel.
- Cruel and Unusual Death: She has her skin ripped yes, ripped from her body. All at once.
- Tagalong Kid: Despite being thirty years old.
The leader of the Cult of Silent Hill, Christabella is a monster to say the least, leading the crazy cult members to burn Alessa at the stake. Now twice as mad and manipulative, Christabella has fooled the condemned cult members that Alessa is a demon, and the only way to survive is to burn people at the stake. She and the rest of the Cult are the targets of Alessa's justified revenge and meet their well-deserved ends in the bloody climax of the film when Rose allows Alessa to enter the chapel and slice and dice Christabella and co. with barbed wire tentacles.
- Big Bad: Gradually revealed to have caused all the misfortune of everyone involved.
- Black and White Insanity: Christabella and her cultists see the world in black and white, refusing to understand how horrible their own deeds are or that the hellish state of the world they live in is their own fault.
- Burn the Witch!: Her modus operandi.
- Cruel and Unusual Death: Christabella is killed by Alessa's barbed wire tentacles which suspend her in midair, enter her body vaginally and anally, exit through her mouth and chest, and rip her in two.
- Decomposite Character: The film removes the evil and fanaticism of the video game version of Dahlia and gives it to Christabella, who doesn't exist in the game.
- Evil Redhead: She's the Big Bad of the first film and has auburn hair.
- Faux Affably Evil: Her serene demeanour is only a mask. She's actually a sociopathic fundamentalist.
- The Fundamentalist: She leads the group of fanatics in Silent Hill.
- Hypocrite: She thinks that burning women that she thinks are witches will avert the end of the world. Not only is this ironically what got her and her followers in their predicament in the first place, but if she was even familiar with scripture, she'd understand that the Apocalypse is God's will. Where the hypocrisy comes in is that she has the nerve to call other people heretics.
- Icy Blue Eyes: Alice Krige wore contact lenses to obtain this effect. They highlight her cold, unforgiving nature.
- Insane Troll Logic: Because her sister wouldn't say who Alessa's father is, she somehow came to the conclusion that she is a witch and had her followers (and their children) persecute her until they decided to end her with a Cruel and Unusual Death.
- Karmic Death: Christabella and her cult followers are massacred by the little girl they burnt thirty years ago. She also enabled the massacre by stabbing Rose in the chest, thus allowing Alessa's Darkness to seep into the church through her blood.
- Knight Templar: Ready to go to any length to uphold God's law.
- Lack of Empathy: As shown by her treatment of Alessa.
- Obliviously Evil: She doesn't realize that she's a villain, instead fancying herself and her cult as being good and "pure" servants of God.
- Principles Zealot: Upholding Purity at any cost.
- Reasonable Authority Figure: Is quite reasonable and even kind to anyone she thinks isn't connected to Alessa. She even helps Rose and Cybil to the hospital, and gives Rose the advice to memorize the map, which later helps her greatly. It's when she discovers that Rose's child is Alessa reborn that she turns on her.
- Religion of Evil: Her cult is Manichaean to the extreme, lacking any trace of forgiveness or compassion for anyone who is seen as impure.
- Sinister Minister: She wears garments and leads the prayers during ceremonies.
- Smug Smiler: She often shows a complacent smile, especially as she's burning people.
- Undignified Death: She begs God to "give her the strength to keep [herself] pure. God's not listening, and Alessa barbed-wire rapes her.
The Apocalypse Maiden and major Woobie, Destroyer of Worlds, Alessa was nine years old when the Cult accused her of being a witch or a demon and had her burnt at the stake. She survived thanks to the sacrifice being botched, and the arrival of her mother and Officer Gucci. Now a vengeance-seeking Little Miss Badass, Alessa has trapped the Cult members in a nightmarish version of the town and split herself into two different other forms: Dark Alessa, her evil side, and Sharon Da Silva, her good side. She lures her good side to Silent Hill to get her revenge.
- Being Tortured Makes You Evil: Or rather, being burned alive does
- Body Horror: The damage done to her burnt body.
- Combat Tentacles: Made of barbed wire.
- Dark and Troubled Past: She was abused by her schoolmates, raped by the school janitor, and then burnt alive by the town's crazy cult of witch hunters.

- Psychotic Smirk: After she saves Rose from a cultist by pulverising him with her barbed wire.
- Reality Warper: Can literally change reality to match her tormented psyche.
- Room Full of Crazy: Alessa's hospital room.
- The Speechless: After being burned, she doesn't speak a word.
- Woobie, Destroyer of Worlds: This poor, poor girl. Mistaken for a witch and tormented for it by her classmates simply because her father was unknown, raped by the school janitor, reluctantly turned over to the cult by her own mother to be burned alive, all of which lead to her growing spiteful of everyone around her and making a pact with a Satanic Archetype to get bloody revenge on the cult responsible for her state.
Sharon Da Silva
The adoptive daughter of Rose and Christopher, Sharon is actually the good side of Alessa. Her strange dreams lead her and Rose to Silent Hill, Sharon disappearing and leading Rose on a wild goose chase around the town of shifting horrors. The Cult try to burn her at the stake, but Rose arrives and has Alessa kill all of them, but Dark Alessa bonds with Sharon, re-creating Alessa.
- All Just a Dream: Rose tries to convince Sharon that everything is just a bad dream. And this after she's been tied up, watched a police officer get burnt alive, and all the cult followers getting massacred by her true self.
- Doorstop Baby: She was left on the doorstep of Toluca Lake Orphanage by Dark Alessa.
- Madness Mantra: "Silent Hill!"
- Nightmare Fuel Coloring Book: Sharon's drawings depict her nightmarish memories of Silent Hill.
The dark side of Alessa, Dark Alessa is a Stringy-Haired Ghost Girl and a Creepy Child, and she knows it. She represents Alessa's anger and desires to have revenge on the Cult. She can manipulate the monsters in Silent Hill, and lures Rose around the town until she reaches Alessa's bedroom in the hospital. When Alessa's revenge finally comes, Dark Alessa relishes in the gore. She later bonds with Sharon to create a new Alessa.
- Blood Lust: She wishes to dance in the blood of the cult members, which she gets to do in the film's climax.
- Creepy Child: And she knows it.
- I Have Many Names: Outright says this to Rose.
- Roaring Rampage of Revenge: And boy, does she want it.
- Satanic Archetype: As the dark being unable to enter the church, and a dark manifestation of the apparent god. However, after a fashion, Satan is Good.
An innocent nurse who cared for Alessa after she was burnt. She took a look at Alessa's burnt body and was unintentionally punished by Alessa's wrath, now forced to bleed from her face constantly. Alessa has since come to regret punishing her.
- Nose Bleed: Also an eye bleed, ear bleed, head bleed, and full facial bleed.
Armless Man (Laying Figure)
One of the several monsters in the film, the Armless Man (or Men) is a featureless humanoid thing with its arms wrapped into its ribcage, making it walk about like someone in a straitjacket. It attacks Rose and Cybil, shooting acid at them. It's based on the Lying Figure monster from Silent Hill 2.
- Hollywood Acid: It takes out Cybil's police helmet, jacket, and shades.
- Not a Zombie: Just LOOK at this guy, and you can instantly question why Cybil would even bother trying to talk sense to it or expect it to obey a police officer.
An army of wailing, burnt, deformed children that approach Rose during the first time the town shifts into the Otherworld. They are Alessa's memories of her classmates, who bullied and harassed her in school.
- Body Horror: Their skin and facial features are twisted around so their faces are on the sides of their heads.
- Creepy Child: They're a bunch of twisted, burnt children who attack anyone they see. This is a given.
Rose encounters an army of twenty odd undead nurses, wrapped in bandages and brandishing weapons. They respond to light and end up attacking each other when Rose sneaks her way through the group to Alessa's hospital room.
- Battleaxe Nurse: They're evil nurses who attack people.
Colin the Janitor
Colin the Janitor was the caretaker of the school Alessa went to. It is implied that he rapes her. He pays dearly, his corpse being found by Rose, strung up in a toilet cubicle by barbed wire. It gets worse when his body comes to life and starts crawling across the floor towards Rose.
- Asshole Victim: It's all but stated later on that he raped Alessa. Nobody's gonna cry for this guy or blame her for granting him a gruesome death.
- Body Horror: Colin is strung up in barbed wire and when his corpse springs to life, we see his legs have been bound to the back of his head, more barbed wire is going into his eyes, and he is forced to crawl about using his hands only.
- Bound and Gagged: The first part anyway, his black tongue often dangles out of his mouth.
- Chained to a Rock: Or chained to a toilet cubicle, and his legs to his head.
- Room Full of Crazy: He died in a toilet cubicle where everything is wrapped in barbed wire and words across the wall read "Dare You! Double Dare You!"
- Walking Wasteland: Colin can rot away anything he touches, as well as summon Creeper insects.
The iconic pyramid-helmet wearing Ensemble Dark Horse, Pyramid Head is an executioner-like monster and the most threatening of the monsters seen in the film (the non-human monsters anyway). He appears twice, but he leaves quite an impression, killing poor Anna outside the chapel.
- BFS: The Great Knife that he carries around with him.
- Impaled with Extreme Prejudice: He tries to do this to Rose and Cybil.
- You Don't Look Like You: While still recognizable, his design was changed greatly compared to his original game. His helmet is a black and girded hexagon, 6-sided version instead of the 7-sided one in the game, and appears much more sharp (claimed by Word of God to be a choice to make it easier for the actor to wear). He wears no gloves, showing normal hands as opposed to fused palms. While his original counterpart walked around in a jerky, pained fashion, here his posture is much more confident. While he still drags his massive knife around, he does not strain nearly as much to do so. This newer design would later be used for his Silent Hill: Homecoming incarnation. Ironically, the design of his knife in Revelations is changed to look like an oversized combat knife like in Homecoming.
