The latest installment in the Halloween series officially hit theaters today. Earlier this year, it was revealed only the first film exists in this world. The rest of the timeline is erased, and the new film picks up in Haddonfield 40 years after the original. While there isn’t any continuation to the seven previous films (nine if you count Rob Zombie’s remakes), that’s not to say the writers didn’t pay homage. Head below for a handful of references to the past films in the series.

Warning: The following article contains major spoilers for the new Halloween film (and other films within the series).

1. Opening credits

The original Halloween begins with slow opening credits. Each name flashes across the screen one by one as the camera slowly zooms in on a jack-o’-lantern. In the new Halloween, the same orange lettering flashes across the screen one by one. However, this time, the pumpkin is positioned in the same place but starts out decomposed. It slowly reanimates back into a jack-o’-lantern as each name goes by.

2. Not family

In Halloween II, Chambers tells Dr. Loomis that Strode is Myers’ sister. The court sealed one of Myers’ files after his parents death, but the Illinois governor authorized them to open it. It states Strode was born two years prior to Myers killing their other sister, Judith. Two years after Myers is committed to Smith’s Grove Sanitarium, their parents die, and she’s adopted by the Strodes.

In the new film, Strode’s granddaughter Allyson’s friends ask if it was Strode’s brother “who murdered all those babysitters.” Allyson responds by stating “that’s something that people made up.” The line erases the belief the duo are related, which creator John Carpenter admits may have been the result of some late-night drinking.

3. Classroom daydreaming

Laurie Strode sits in the back of class in the first Halloween, daydreaming out the window as one does during a boring lecture. She locks eyes with Michael Myers as she peers outside. The teacher calls her attention back to class, but when she looks out again, Myers is gone. In the new Halloween, Strode’s granddaughter Allyson also takes a seat in the back of the class. She too stares out the window, but instead of Myers, she’s sees Strode appear and disappear.

4. Escaped patients

In the original film, Dr. Loomis heads to Smith’s Grove Sanitarium to meet with Myers, who is his patient. As he approaches the facility with Chambers, they see that the patients are wandering down the road in the rain.

The same scenario happens in the new film where a father and son are driving home late at night. They round a corner and witness Smith’s Grove patients who are now loose after Myers crashes the bus transporting them.

5. Laurie Strode’s song

In the original movie, Strode’s father is a realtor who asks her to drop a key off at the old Myers house. Strode runs into the kid she babysits, Tommy Doyle, on the way. After dropping the key and parting ways, she begins singing to herself: “I wish I had you all alone/Just the two of us.” Over her shoulder, Myers appears and begins his menacing heavy breathing. Allegedly, the reason actress Jamie Lee Curtis sang this song was because with a famously low-budget production, the crew didn’t want to spend money on buying the rights to music. In the new film’s aforementioned father-son scene, just before they stumble across the escaped patients, they’re talking and listening to the radio. Director David Gordon Green had a band write a version of Curtis’ tune, which can be heard in their car.

6. The gas station massacre

Halloween 4: The Return Of Michael Myers picks up 10 years after Halloween II (ignoring the attempted spinoff Halloween III: Season Of The Witch) with Myers still recovering from a fire that burned him. He’s sent back to Smith’s Grove Sanitarium, but once he overhears Strode died in a car crash and has a daughter, Jamie, he breaks loose and crashes the ambulance. Loomis hears of his release and heads back to Haddonfield, stopping at a gas station along the way. There, he discovers Myers murdered the mechanic to replace his iconic navy jumpsuit as well as other employees. Loomis faces off with Myers for their first showdown since the hospital 10 years prior.

In the new Halloween, an investigative journalist duo set out to make a podcast about Myers. Once he escapes, he heads to a gas station where he once again kills employees including a mechanic for his jumpsuit. He faces off with the duo, eventually reclaiming his iconic mask, which they borrowed from the attorney general.
