By eschewing the nine(!) sequels separating John Carpenter’s Halloween from the 2018 follow-up, the latter group of filmmakers (which includes writer/director David Gordon Green, writer Danny McBride, producer Jason Blum, and Carpenter himself in an executive producer role) have freed themselves from four decades of the slasher series’ tangled canon.

Audiences are simply asked to forget the events of Rob Zombie’s 2007 remake (and its lesser sequel), the “Cult of Thorn” arc that link Halloween’s 4-6, and even the well-received 20th anniversary Halloween H20, itself a sequel that ignored the events of four prior films.

That’s not easy to do, though it should be noted that fans have likely erased their memories of H20’s follow-up, Halloween: Resurrection, in which series villain Michael Myers faced off with a karate-kicking Busta Rhymes.

Yet, by making the new Halloween a direct follow-up to the 1978 original, Green and company are raising questions that will deserve answers once the film bows on October 19.

Chief among them: How was Michael Myers captured following his disappearance at the end of the first film? For those who haven’t gone back recently, in the climactic moments of Carpenter’s Halloween, Myers was shot by his psychiatrist, Sam Loomis (Donald Pleasance), and fell from the second-floor balcony of a home in which he’d cornered Jamie Lee Curtis’ Laurie Strode.

However, when Loomis goes to inspect the body he finds Myers gone, setting up the first sequel, which picks up at that very moment.

The 2018 Halloween trailer opens with a pair of investigative journalists visiting Myers in a prison/asylum. How he ended up there? Only the filmmakers know, for now.

On that note, how will the sequel explain Loomis’ fate? Pleasance’s character is referenced in the trailer, and if he wasn’t killed at the end of 1981’s Halloween II (again, it’s been wiped from canon), the new film should reference what became of Loomis.

Judging by the trailer’s approach to Laurie Strode – she’s armed and waiting for Myers to escape – it appears the one-time “final girl” has assumed Loomis’ role as the series’ Van Helsing, the hunter/harbinger, prepared to face her mortal enemy while warning the rest of fictional Haddonfield, Illinois of their approaching doom.

For fans who still hold the sequels (or at least, some of them) close to their hearts, they can take comfort in the fact that this new Halloween is peppered with homages and Easter eggs they’ll surely recognize, if they’re paying attention.

Here are six that stood out from the first trailer:

1. Wandering Patients

Myers’ escape in the sequel is the result of a yet-to-be explained bus accident. The trailer shows a family in their car braking suddenly when the killer and his fellow asylum patients are wandering in the road.

The scene bears resemblance to the opening of the 1978 film, in which Pleasance’s Loomis and Nancy Stephens’ Nurse Chambers come upon the escaped patients of Smith’s Grove Sanitarium.

2. Sibling Rivalry

While Laurie Strode’s connection to Michael Myers initially felt forced in the first Halloween sequel – the two are brother and sister, with Laurie put up for adoption after he committed murder as a 6-year-old – the familial bond went on to become a critical thread in chapters 4-8 and Zombie’s films.

In the new trailer, a character hints at the relation between killer and survivor, until Strode’s granddaughter, Allyson (Andi Matichak) responds, “that’s something that people made up.”

Unless there’s a curveball coming in the finished film, this is just another way Halloween’s writers are tipping their caps to the series’ fans.

3. Restroom Horror

In the trailer, Myers is seen terrorizing one of the investigative journalists inside a gas station restroom. Fans of the series will immediately be reminded of a scene in Halloween H20 in which Myers stalks a mother and daughter in a restroom, only to steal the keys to their car.

The scene could also be a reference to Zombie’s Halloween, in which Myers acquires his familiar coveralls in a to-the-death fight with Ken Foree’s Joe Grizzly.

4. Watch Where You’re Going

Another trailer callback to the first Halloween occurs when a pair of trick-or-treaters run into Myers on the sidewalk. The scene in the trailer (at 2:00) even makes use of Carpenter’s original score, and mirrors the moment in 1978’s Halloween when young bully Ritchie Castle (Mickey Yablans) runs into Myers.

A similar scene occurs in Halloween II when a young boy carrying a boom box (Lance Warlock) accidentally crosses paths with Myers.

5. Ghosting

One of the iconic scenes in Carpenter’s Halloween sees Myers approaching his victim in the guise of her boyfriend, wearing a “ghost sheet” with two eyeholes cut out.

The trailer shows a similarly dressed shape waiting in a chair as Will Patton’s cop surveys a bedroom. We’ll have to wait until October 19 to see who’s under the sheet.

6. Silver Shamrock is Back!

The decision to abandon the Michael Myers character and go with a brand new storyline for 1982’s Halloween III: Season of the Witch is one that flummoxed critics and audiences back in the day.

Those in line to see babysitters stalked by a killer were instead treated to a somewhat incomprehensible plot to murder the children of the world using Silver Shamrock brand Halloween masks fitted with microchips and pieces of Stonehenge.

It’s a Twilight Zone-meets-Body Snatchers plot that never quite comes together and derailed the franchise just as Friday the 13th and Nightmare on Elm Street would begin to dominate the 80s slasher scene.

Decades later, Season of the Witch has found its cult audience, and fans looking closely at the just-released trailer will notice — for a split second at 2:07 — children running in fear wearing the classic Silver Shamrock masks.
