The main and title character. He returns to his home in England after his brothers murder. He wishes to look into it, and of course is bitten by a werewolf. He finds out his father was the werewolf who bit him, killed his brother, and his mother.
Adaptational Badass: His Wolfman is far more formidable than in The Wolfman 1941, killing about 10 times the number of people the original Wolfman did. Even in human form he's not bad with a rifle.
The Alcoholic: He comes off as this in the movie. Played pretty straight in the book adaptation of the movie.
All Just a Dream: He has quite a few hallucinations while recovering from his nasty little bite, as well as hallucinations in the asylum.
Dark and Troubled Past: You've had quite a nice little messed up childhood, haven't you? What with witnessing your mother's death and all, and being sent to a mad-house where you underwent all sorts of nasty treatments and then shipped off to live with a distant relative in America.
Fake Memories: As a child, his memories of his mother's death were re-formed during his time in the asylum so he would believe that his mother killed herself and concealed his real memories of his werewolf father tearing her throat out.
Go Among Mad People: He gets locked in an asylum for ranting that he's a werewolf. He'd previously been committed as a boy, to help him suppress the trauma of his mother's death, because he'd been ranting (quite truthfully) that his father was a werewolf and had killed her.
I Cannot Self-Terminate: When the full moon rises, Lawrence, strapped to a chair, implores the doctors in the room to kill him because he knows he will go on another murderous rampage when he transforms.
In a Single Bound: He quite impressively clears a police blockade in a single leap, much to Aberline's dismay.
Instant Sedation: Subverted. He gets a number of injections while in the asylum, presumably to sedate him, but none take effect immediately. When a doctor tries to inject him with a sedative as he turns into a werewolf, he isn't affected at all.
It's Personal: In relation to his own father, who is revealed to have killed his wife and oldest son and bit Lawrence, thus spreading the curse to him.
I Want My Mommy: In the novelization, he begs his dead mother to help him during his first transformation, in pain and scared out of his mind. Eventually he just takes to screaming her name, but all that comes out is an animal roar.
Laser-Guided Amnesia: It's not so much that he forgot, but rather Lawrence's memories were re-wrote so that real memories of his werewolf father killing his mother were made to appear that she had killed herself with a razor.
Let Them Die Happy: He dies in the end, but he stays alive for a few moments to reassure and thank Gwen for "setting him free." However, he dies before learning that he has bitten Aberline and cursed him as well. He could also be happy from realizing that since he was still alive to that point meant he had succeeded in defeating his father, meaning neither of them will hurt anyone again. However, this only makes the ending more tragic when we find out what becomes of Aberline.
Madness Mantra: Where is my father? Where is my father? WHERE IS MY FATHER?
Mind Rape: What essentially happens to him after his time in the asylum, poor man.
Not Even Bothering with the Accent: Justified, since in this version he spent most of his life in America where his accent probably dissipated. Since Benicio is a native Spanish speaker, his accent does seem to slip in a few scenes with varying degrees, which in turn might be justifiable as well, since his mother in this version was visibly of some Spanish decent. He still gets Brownie Points for a good effort.
Parental Abandonment: He witnessed his mother's "suicide" as a child, and if that's not traumatic enough, his father throws him into an asylum and then ships him off to live with his aunt in America afterwards.
Power of Love: His feelings for Gwen bring out what's left of his humanity, but only right before Gwen "sets him free."
Shapeshifter Baggage: The novelization of the movie makes note of the extra mass he gains when transforming into a werewolf, and suggests its source is hell itself.
Famous Last Words: "You're heir to my kingdom, Lawrence. You've always been heir to my kingdom."
Hannibal Lecture: Gives one to Lawrence. Rather fitting considering he's played by Anthony Hopkins
Notable Non Sequitur: He warns his son not to go out on the full moon, which sets up the inevitable werewolf attack. The Notable part of this is where he tells Lawrence this because Sir John is the werewolf and (at least, initially) doesn't want to be responsible for his remaining son's death.
Papa Wolf: An instance of this occurs when he tries to protect Lawrence from the angry mob trying to capture him by shooting at them, and possibly even blinding someone in the process, showing that he may truly care for his son. Highly subverted when he ends up trying to kill Lawrence later on after revealing he already killed his brother and mother... and that he's a werewolf himself... Trauma Conga Line much? Also subverted when he lets the angry mob drag Lawrence off to an insane asylum right after the poor guy wakes up after the full moon and is scared and confused.
Pater Familicide: Given that he is the one who killed his wife and Ben and probably would have succeeded in killing Larry if the hunters hadn't come along...
Lawrence's love interest. Ben's former fiancce, who wants to know the truth about Ben's death. Overtime they get romantically attached. After finding out Lawrence is a werewolf, she sets out to help him, and ends up killing him.
Action Girl: She eventually becomes the Victorian equivalent of this when she becomes so motivated by trying to save Lawrence that she totes a gun around while running around in a dark forest in the middle of the night — certainly breaking the Damsel in Distress version of her character from 1941.
Adrenaline Makeover: She gradually gets this over the course of the movie. Initially, she comes off as a very proper and somewhat quiet woman. However, as she becomes determined to find a cure for Lawrence towards the end of the movie, she starts to wear less fancy attire and her hair is noticeably a little unkempt from her nights of searching for answers. By the finale, her hair is down, she is wearing a slightly lower cut and dirtier looking dress than her earlier attire, and carries around a silver bullet loaded pistol.
Always Save The Guy: Her actions in protecting Lawrence from Aberline are understandable, but she is also putting the chance that he can be cured above the likelihood that he will kill again (and in fact Lawrence does end up infecting someone directly because of her.)
Nice Job Breaking It, Hero: She stops Aberline from shooting Lawrence, which in turn causes him to get bitten. However, this really doesn't do much good since she ends up shooting Lawrence herself in the end. Although, she's somewhat justified since she was still convinced she could reach Lawrence, and well... she was right. Plus, she probably figured that Lawrence would have finished off Aberline instead of chasing after her instead.
Only I Can Kill Him: After many days of sleepless research, she discovers only how to kill Lawrence, not how to cure him. In desperation she searches for the Gypsy fortune-teller, but she only confirms it: a werewolf can only be slain with silver, and only by someone who loves him.
Inspector Francis Aberline
Based on the real life Inspector Fredrick Aberline of the Jack the Ripper murders, Francis is incharge of the investigation of the werewolf murders. He is suspects Lawrence as being the killer, which he technically is. He soon learns the truth and becomes bitten himself.
Anti-Villain: He antagonizes Lawrence, but is technically one of the good guys.
Foreshadowing: He shoots a standing mirror which he thinks Lawrence Talbot is hiding behind. "Now there's some bad luck for ya," an officer says regarding the broken mirror. Near the end of the movie, Aberline is bitten by Lawrence, thus doomed to become a werewolf himself.
God Help Us All: Upon the seeing the Wolfman escape a barrage of gunfire during the London rampage.
Hero Antagonist: He's just a cop doing his job and trying to stop Lawrence from killing again.
Cue the Flying Pigs: He is lecturing about the strapped-down Lawrence Talbot remarks that his patient can no more transform into a monster than he, the doctor, can sprout wings and fly out of the window. Sure enough, when Talbot transforms and breaks loose, he invokes Destination Defenestration on the shrink.
Death by Irony: He claims that Lawrence will no more likely change into a werewolf than he is likely to sprout wings and fly out the window! He doesn't sprout wings at any rate...
Battle Butler: He is armed to the teeth with silver bullets and other monster-killing devices. It didn't do him much good in the end though, and he loses points for not realizing the silver bullets are sabotaged.
Secret Keeper: He knows Sir John is the Wolfman and kept him restrained during nights
