18 details you probably missed in 'Scream'

During their first conversation, Mr. Prescott tells Sidney that he'll be staying at the Hilton by the airport.

Later on, when Dewey says he isn't registered there, it's suggested that Sidney may be wrong about which hotel her father was staying at. But viewers who were paying attention earlier will realize she's correct.

When Sidney's father tries to enter her room at the beginning of the movie, her closet door is open, preventing him from opening her bedroom door.

She uses the same trick later to stop Ghostface from getting into her room.

In another foreshadowed moment, she runs upstairs while Ghostface is attacking her.

This goes directly against a comment she made earlier in the film where she made fun of horror-movie characters who run farther into a house instead of escaping outside.

When Sidney's being attacked in her house, she contacts the police via her computer.

She types out an emergency message using a teletypewriter (TTY), which is most commonly used by people who are deaf to make phone calls.

Since users on both sides of a conversation can type out their message instead of speaking out loud, it's also apparently a great tool if you don't want to draw attention to yourself while there's a killer in your house.

When Sidney is at the police station after being attacked, she sits at Dewey's desk, which has a child's sheriff hat, toy handcuffs, and a toy police car on it, along with the cover of "Comic Cops" taped to his computer.

Dewey's desk is the only one in the station with any kind of toys on it, a detail that reinforces his later complaints about being viewed as less mature than the other cops.

When Sidney arrives at school the morning after being attacked, one reporter tries to interview her, saying that the townspeople "have a right to know" about the attack.

This reporter is played by Linda Blair, who famously played the possessed child in "The Exorcist."

Billy even mentions watching the film earlier in the movie.

When Tatum, Sidney, and Stu are standing by the lockers, the insides of Sidney and Tatum's lockers are visible.

Sidney's is barely decorated, aside from one photo, but Tatum's has stickers, photos, and magazine pages hung up.

The contrasting locker decor adds another level to the two girls' opposite styles.

When Principal Himbry looks down the hallway, he sees a janitor named Fred cleaning.

The janitor is wearing a red-and-green striped sweater which, combined with the name Fred, seems to be a clear reference to Freddy Krueger from "Nightmare on Elm Street."

Fred is played by Wes Craven, the director of "Scream," who also wrote and directed "Nightmare on Elm Street."

The characters mention real horror movies constantly throughout the film, from discussing the killers in "Halloween" and "Friday the 13th" to using the same iconic prop for fake blood from "Carrie."

Billy also quotes "Psycho" and the teens are all shown watching "Halloween" during the party scene.

Throughout the film, more than 15 movies are mentioned by name.

The Woodsboro high-school name and colors appear in multiple scenes.

When Steve is first shown, he's wearing a yellow-and-blue letterman jacket that other students are shown wearing during the school scenes.

There's also a yellow-and-blue bench in front of the school, and Tatum can be seen holding a yellow-and-blue Woodsboro High School book at her locker.

When Tatum and Sidney are talking about Sydney's mother's death, Tatum tells Sidney she sounds like a "Wes Carpenter flick."

Wes Carpenter isn't a real-life horror-movie creator. But the name seems to be a combination of "Scream" director Craven and "Halloween" director John Carpenter's names.

When Dewey takes Tatum and Sidney to the grocery store, he drives in the middle of a road that has parked cars facing the same way on both sides — indicating that it is likely a one-way street.

But there's a warning to slow down for school traffic written in the opposite direction on the street, which would only be necessary for two-way traffic.

Dewey and Sidney joke about who would play Sidney in a movie version of her attack.

Sidney complains that with her luck, they would cast Tori Spelling.

Spelling does indeed end up playing Sidney in the "Stab" films, which are the in-universe movies that recreate the events of "Scream."

When Dewey and Sheriff Burke talk outside of the grocery store, Dewey is holding an ice-cream cone and the Burke has a cigarette.

Every time Burke goes to take a smoke, Dewey licks his ice-cream cone.

The moment, again, shows Dewey as more juvenile than the other cops in the town.

When Randy explains the rules of horror movies, Kenny watches the feed in the van.

Randy's line about why Laurie escapes from Michael Myers in "Halloween" is different from the recording that plays.

He originally says, "That's why she always outsmarted the killer in the big chase scene at the end. Only virgins can do that."

The line that is shown on the feed in the van is, "Only virgins can outsmart the killer in the big chase scene at the end."

During Ghostface's staged attack on Billy, Billy seems to be stabbed and covered in blood.

But his shirt is clearly not ripped or torn from the supposed knife.

Although Sidney didn't have time to notice this during the attack, she still doesn't realize it later when she's right next to Billy on the staircase.

When he explains horror-movies rules, Randy says that if a character says they'll "be right back," they're going to get killed.

Stu mockingly says he'll be right back, and Randy says he'll end up in the kitchen with a knife.

Stu is later stabbed with a knife in the kitchen, and he does indeed end up dying while fighting Sidney.

After Billy talks to Sidney on the house phone, he throws it and it hits Stu.

When Stu yells that Billy hit him with the phone, that line was actually improvised by actor Matthew Lillard. Skeet Ulrich, who played Billy, accidentally really hit his costar with the prop.

Stu and Billy both kill people while wearing the Ghostface costume in the original "Scream." But viewers who are paying close attention can tell who's wearing the costume in different scenes by the way they hold the knife.

Stu uses both hands to grip it, but Billy only uses one.
