Why Did Billy Kill Casey In Scream Unpacking The Motives

The 1996 slasher film Scream, directed by Wes Craven, redefined the horror genre with its self-aware script, sharp dialogue, and brutal opening sequence. The murder of Casey Becker—often mistakenly referred to as “Casey” alone—is not just a shock tactic; it's a calculated narrative decision that sets the tone for the entire franchise. But at the heart of this scene lies a disturbing truth: Casey is killed by someone she trusts—her boyfriend, Billy Loomis. Understanding why Billy commits this act requires examining his psychology, motivations, and the film’s deeper commentary on media, trauma, and toxic masculinity.

The Shock of the First Victim

In traditional horror films, the first death often belongs to a peripheral character—a minor player whose demise signals danger but doesn’t emotionally engage the audience. Scream subverts this expectation by making Casey Becker a central figure in the opening 15 minutes. Viewers spend time with her: answering a chilling phone call, trying to follow horror movie rules, and ultimately pleading for her life. Her death is personal, prolonged, and devastating.

What makes it even more jarring is the reveal: Billy, her seemingly concerned boyfriend, orchestrated the entire scenario. He wasn’t coming to save her—he was watching, waiting, and ultimately responsible.

Tip: Pay attention to early dialogue in horror films—subtle clues about character motives are often hidden in casual conversations.

Billy’s Psychological Profile

Billy Loomis isn’t a random psychopath. He’s intelligent, articulate, and deeply disturbed by what he perceives as moral decay in society—especially surrounding sex and media violence. His motive stems from a warped sense of justice. In his mind, Sidney Prescott’s mother, Maureen, destroyed his family by having an affair with his father. This betrayal fuels years of resentment, which he projects onto Sidney and, symbolically, onto Casey.

Casey’s murder serves multiple purposes in Billy’s plan:

• Punishment: She represents teenage sexuality—answering the phone while wearing lingerie, engaging in flirtatious banter. To Billy, this behavior is morally corrupt.
• Manipulation: By killing Casey, he inflicts emotional trauma on Sidney, whom he both loves and resents.
• Performance: The murder is staged like a horror movie, fulfilling his obsession with cinematic tropes and control.

Billy sees himself not as a murderer, but as an avenger enacting poetic justice. As he later tells Sidney: “Movies don’t create psychos. Movies make psychos more creative.” This line reveals his twisted worldview—he believes he’s merely following a script written by culture itself.

“We wanted Billy to be more than a monster. He’s a product of repressed anger, media saturation, and a breakdown in family values.” — Kevin Williamson, screenwriter of Scream

Narrative Function of Casey’s Death

From a storytelling perspective, Casey’s death accomplishes several critical goals:

1. Establishes stakes: No character is safe, regardless of popularity or screen time.
2. Introduces the rules: The infamous “rules of surviving a horror movie” are introduced during her phone call with Ghostface.
3. Builds suspense: The slow build-up—phone calls, questions about films, mounting tension—creates unbearable anxiety.
4. Subverts expectations: The killer is not a stranger, but someone close, undermining trust within relationships.

This sequence also functions as a meta-commentary on audience expectations. Viewers anticipate a masked killer emerging from the shadows. Instead, they’re shown how evil can wear a familiar face—someone who says “I love you” moments before orchestrating a murder.

Do’s and Don’ts of Horror Tropes (As Demonstrated in Scream)

Trope	Do (Used Effectively)	Don't (Avoided)
First Death	Kill a sympathetic, well-developed character early	Kill a forgettable extra with no emotional impact
Killer Identity	Hide identity behind red herrings and plausible suspects	Reveal too early or rely on supernatural elements without setup
Sex and Death	Link them thematically (moral judgment), not automatically	Punish all sexually active characters predictably
Audience Awareness	Use knowledge of horror clichés to deepen tension	Assume viewers won’t notice plot holes or inconsistencies

The Role of Media and Misogyny

Billy’s actions cannot be separated from the film’s critique of media influence and patriarchal control. He blames movies for glorifying violence, yet uses those same narratives to justify and choreograph his crimes. His hatred toward Maureen—and by extension, Casey and Sidney—is rooted in slut-shaming and male entitlement. He cannot accept that women have autonomy over their bodies or choices.

Casey’s final moments underscore this theme. She’s punished not because she breaks a horror movie rule, but because she fails to conform to Billy’s moral code. When she refuses to say “I want to fuck you,” despite being threatened, she still dies—not for defiance, but for existing in a space of sexual agency.

This reflects a broader societal issue: the criminalization of female sexuality. Billy positions himself as a moral arbiter, but his actions expose deep-seated misogyny masked as righteousness.

Tip: Analyze horror films through a sociological lens—they often reflect real-world fears and cultural anxieties.

Mini Case Study: The Phone Call Scene

The now-iconic phone call between Casey and Ghostface is studied in film schools for its mastery of tension. A realistic suburban home, dim lighting, and escalating questions about horror trivia lull the viewer into a false sense of familiarity. Then, the camera pans outside—revealing Billy on a payphone across the street, watching through binoculars.

This moment reframes everything. What seemed like a random attack becomes a premeditated act of surveillance and control. It mirrors real-life stalking behaviors and highlights how technology enables manipulation. Billy doesn’t need to enter the house to exert power—he controls the situation remotely, turning intimacy into terror.

In real-world terms, this parallels digital harassment and coercive control in abusive relationships. Billy’s crime isn’t just physical—it’s psychological warfare disguised as romance.

Step-by-Step: How Billy Executed the Plan

1. Scouted the location: Knew Casey would be home alone, assessed escape routes.
2. Prepared equipment: Used a burner phone (payphone) to avoid traceability.
3. Staged the call: Engaged Casey in a game-like conversation, building fear gradually.
4. Coordinated with Stu: Ensured Stu would arrive later to play the second killer, creating confusion.
5. Observed the murder: Watched from a distance, maintaining emotional detachment through voyeurism.
6. Played the grieving boyfriend: Arrived “too late,” feigning shock and sorrow.

This meticulous planning underscores Billy’s intelligence and cold calculation. Unlike Jason Voorhees or Michael Myers, he doesn’t act on impulse—he crafts a narrative where he is both director and participant.

Frequently Asked Questions

Was Casey aware that Billy was the killer?

No. There is no evidence Casey suspected Billy. She believed he was on his way to help her. Even during the phone call, she references him as her safety net, saying, “My boyfriend’s coming over.”

Did Billy love Sidney, or was it all manipulation?

Likely both. Billy exhibits signs of obsessive attachment. His love is possessive and conditional—rooted in control rather than care. He wants Sidney to suffer, but also to belong to him exclusively.

Could the police have prevented Casey’s death?

In the context of the film, no direct intervention was possible—the call wasn’t traced in time. However, the film critiques institutional failure: the sheriff dismisses early warnings, reflecting real-world underestimation of domestic threats.

Conclusion: Why It Still Matters

The murder of Casey Becker remains one of the most impactful openings in horror history—not because of gore, but because of betrayal. Billy didn’t just kill a girl; he shattered the illusion of safety in everyday life. His motives are complex: a mix of revenge, ideology, performance, and deep psychological damage.

Scream forces audiences to confront uncomfortable truths: that monsters can look like boyfriends, that trauma breeds violence, and that pop culture both reflects and shapes our darkest impulses.
