Sandy never explains in detail why she did not return to Australia.
Sandy suddenly appears at Rydell High.
Paramount Pictures
During the opening montage at the beach, Danny and Sandy end their summer romance.
Sandy intends to return to Australia, but she winds up attending Rydell High instead.
Sandy’s only reason for why she is not in Australia when she and Danny reunite at Rydell is a “change of plans.”
The first glimpses of Rydell High paraphernalia are shown in the animated renditions of the characters’ rooms.
The school’s name is hinted at during the opening sequence.
Universal Pictures
Rydell High School, where the majority of the film is set, is first seen on pennant flags in Danny and Rizzo’s rooms during the animated opening credits.
The paraphernalia indicates that the colors of the imaginary institution are red and white.
It appears that Sandy’s animation scene references two famous Disney films.
It appears to make reference to Cinderella and Bambi.
Universal Pictures
During Sandy’s animation segment, she is depicted waking up and dressing with the assistance of jovial woodland animals.
The two birds that assist her in donning a blue dressing robe appear to be a reference to a similar scene in “Cinderella” (1950).
When she sits at her vanity, there are a deer and a rabbit in her room that are reminiscent of “Bambi” characters Bambi and Thumper (1942).
The animated sequences contain several references to real individuals and businesses.
A few references to the late 1950s are present.
Universal Pictures
Throughout the opening credits, political references, celebrities, and brand names from the 1950s are displayed.
The references consist of a Dwight D. Eisenhower “I Like Ike” campaign button, a famous portrait of Marilyn Monroe, a James Dean poster, many Lucky Strike cigarette advertisements, a Pepsi-Cola billboard, and a Firestone billboard.
The actors who portray the T-Birds and Pink Ladies are far older than the average high school student.
The actors were significantly older than their roles.
Universal Pictures
Nearly all of the principal players in “Grease” are far older than high school age.
John Travolta, who was 23 years old, was one of the younger major actors, while Olivia Newton-John was 29.
Jamie Donnelly (Jan), who was 30, Michael Tucci (Sonny), who was 32, and Stockard Channing (Rizzo), who was 33, were among the actors in their 30s when the picture aired.
The name of The Pink Ladies is displayed on-screen multiple times before being spoken aloud.
The school cliques are immediately apparent.
Universal Pictures
In the animated opening sequence, Rizzo’s room contains a framed certificate that reads Pink Ladies, the first reference to the film’s eponymous female group.
The name is then shown on the females’ jackets as they walk to Rydell, prior to any mention of the clique.
On the first day of school, Kenickie pranks a girl in homeroom.
He places a replica snake in her purse.
Universal Pictures
On the first day of school, during homeroom, Kenickie places a fake snake in a girl’s handbag without her seeing.
The girl is the sole student seated at the table with her bag, making her an easy target. However, it seems she would have noticed Kenickie sprinting alongside her.
Throughout the film, Rizzo wears several pairs of red shoes, but one pair appears to be damaged.
Her straps are little worn.
Universal Pictures
As the head of the Pink Ladies, Rizzo has a bolder appearance than the other girls.
She frequently wears red shoes, which Sandy replicates for the last scene.
However, in a previous scene, Rizzo’s signature shoes appear to be somewhat damaged.
During “Summer Nights,” the left shoe’s upper strap is visibly torn, whilst the right shoe is in pristine condition.
The school spirit bonfire is not particularly lively.
The pep rally was not especially spirited.
Universal Pictures
With the exception of the conflicts between Danny’s group and a rival gang, “Grease” is a rather positive film.
However, the kids at Rydell High’s bonfire cheer rally are oddly hostile in their support.
Most school spirit moments in movies focus on cheering for the team, but this scene has more placards displaying animosity toward the Rydell High Rangers’ rival than support for the squad.
Students carry signs reading “Rest in Peace” and “Death to the Gladiators.” Even a doll representing the opposite team’s players is being burned.
Two faculty members at Rydell High have opposing views to Coach Calhoun’s lecture.
The women have a different reaction.
Universal Pictures
At the pep rally, Coach Calhoun delivers a speech that takes an aggressive approach to school spirit.
He describes tearing the opposing team apart and slaughtering them.
Before the principal catches her, the assistant principal’s eyes light up as she listens to him, and she even appears to smile at his remarks.
In contrast, the principal does not even attempt to put on a smile. She appears startled by both the speech and her colleague’s response.
One of the T-Birds is armed with a real knife, while another is armed with a water pistol.
Their weapon selections are somewhat distinct.
Universal Pictures
The T-adversaries, Bird’s the Scorpions, first appear at the Rydell bonfire.
Kenickie pulls out a knife and asks the T-Birds whether they believe the Scorpions are looking for a fight when he finds them.
Doody takes out a water gun, despite Kenickie appears to be the only member of the group possessing a real weapon.
Rizzo’s jeans are cuffed like the T-Birds’.
A few of Rizzo’s dress choices resemble those of the guys.
Universal Pictures
The T-Birds cuff the bottoms of their jeans throughout the film, a fashion characteristic of the 1950s.
Rizzo also wears cuffed jeans to the bonfire, but none of the other girls appear to follow suit.
This element may have been intended to emphasize her role as head of the Pink Ladies and portray her as a fierce “guy’s girl.”
Sandy’s ears are pierced by Frenchy with a virgin pin.
A Pink Lady possessed the pin.
Universal Pictures
When Frenchy desires to pierce Sandy’s ears, Marty provides the girls with her virgin pin.
Jan jokes that Marty no longer requires her virgin pin, implying that she is sexually active.
In the 1950s and 1960s, the round pin was popular among women. It was typically a show of affection from her boyfriend, but it also indicated that she was a virgin.
Typically, if she wore it on her left side, it indicated that she was a virgin, whereas if she wore it on her right side, it indicated that she had “gone all the way.”
The plastic pool in Frenchy’s garden makes little sense.
Uncertain as to why Frenchy has a pool in her garden.
Universal Pictures
Sandy exits the overnight at Frenchy’s and enters the backyard, where she ends up singing by a kiddie pool.
Frenchy may have utilized the pool to cool down throughout the heat. However, it is now autumn, and the majority of the characters are depicted wearing heavy jackets.
Someone appears to have also cleaned the kiddie pool. Despite the abundance of trees in her yard, no leaves have fallen into the lake.
Firestone tires are heavily featured throughout the film.
Several brands are visible throughout the film.
Universal Pictures
During the animated opening credits, an advertisement for Firestone tires first appears on a billboard.
In “Greased Lightning,” the T-Birds’ tires prominently display the Firestone brand name and insignia.
Even after the drag race, Leo’s car window bears a Firestone brand sticker.
Sonny makes a joke indicating that the duration of intercourse with him is fifteen minutes.
Sonny makes a dirty joke.
Universal Pictures
Danny informs the T-Birds that girls are “just good for one thing,” to which Sonny responds, “Then what are you meant to do with them for the remaining 23 hours and 45 minutes of the day?”
Men howl with delight at the joke, which indicates that Sonny’s sexual experiences last 15 minutes.
According to Healthline, sex therapists consider seven to thirteen minutes to be the “ideal” duration for penetrative, vaginal sex; hence, despite his crudeness, Sonny’s encounters are rather typical.
In one scenario, Rizzo has unblended powder on her face, and another Pink Lady applies her cosmetics in the dark.
Her application of cosmetics is not always immaculate.
Universal Pictures
At the diner, when applying makeup, Rizzo only blends a portion of the substance, leaving spots of powder on her cheek and nose.
Previously, during the school’s bonfire, another Pink Lady was applying her cosmetics in total darkness.
Given these bizarre cosmetic selections and Frenchy’s failure to colour her hair correctly, it is evident that the Pink Ladies’ success is not based on their beauty talents.
Doody refers to a well-known dancing pair.
The students participate in a dance competition.
Universal Pictures
During the school’s dancing competition, a reporter observes Danny and Sandy’s amazing abilities.
On the dance floor, the man approaches Frenchy and Doody to learn more about them. Doody, however, jokes that Danny and Sandy’s names are Fred and Ginger, a reference to the renowned 20th-century dance couple Fred Astaire and Ginger Rogers.
Sonny adds alcohol to the punch at the dance.
Spiking the punch is a typical dance scene cliche in high school.
Universal Pictures
Sonny can be seen momentarily adding booze to the punch at the dance competition.
When a chaperone finds Sonny beside the bowl, he claims that he was simply washing his hands, an odd explanation that the teacher accepts.
During the drive-in sequence, the original trailer for “The Blob” is partially displayed.
The protagonists view a film at a drive-in theater.
Universal Pictures
During the drive-in sequences, the original trailer for “The Blob” plays in its entirety.
Since the picture was released in 1958, about the same time as “Grease,” the trailer makes sense.
Rizzo informs Marty of her pregnancy with a witty contrast.
She incorporates 1950s humor.
Universal Pictures
Rizzo tells Marty in the drive-in bathroom that she “feels like a malfunctioning typewriter.”
Marty can not comprehend her meaning, but Rizzo explains that she missing her period and believes she is pregnant.
Mrs. Murdock, the shop teacher, is heavily involved in the T-antics. Bird’s
She aids in the installation of stolen parts.
Universal Pictures
Mrs. Murdock is typically introduced on the first day of school, wearing her Rydell High Auto Shop coveralls.
Despite being their teacher, she participates in some of the T-Birds’ illicit actions, such as installing stolen parts in Kenickie’s car.
She even attends the drag race with them, despite the illegality and risk of the activity.
A girl with an odd hairstyle can be seen in the background of the carnival scene.
It appears like she has balloons attached to her hair.
Universal Pictures
At the beginning of the carnival scene, a background girl has balloons attached to her hair.
At one point, her ponytail gets hoisted by the peculiar adornment, and as she walks, her hair bobs up and down beneath the balloons.
Although the aesthetic is somewhat eccentric, the carnival setting partially justifies it.
The conclusion with the flying car was actually predicted earlier in the story.
Earlier, a comment is made concerning a flying car.
Universal Pictures
Mrs. Murdock observes Kenickie’s car prior to the race and remarks, “If it were in better condition, it would fly.”
It sounded like a throwaway pep talk at the time, but as Danny and Sandy fly away in his car at the end of the film, the statement jumps out more.
