Jessica Wilson

“Grease”, the iconic musical that captured hearts in 1978 and remains an enduring favorite, left an indelible mark on the world of cinema. Its vibrant dances and sing-along tunes continue to dazzle audiences to this day. 

However, even this beloved classic is not exempt from the occasional misstep. Every cinematic gem, no matter how brilliant, has its hidden imperfections. Some are discreet, while others may elude all but the most discerning eye. 

Join us as we journey back to Rydell High to find out these intriguing mistakes that lie beneath the surface of “Grease.”

#1. Sudden changes of location

Do you remember the scene where Sandy and Danny stand on the beach? Take a closer look, you will notice that the position of Danny is changed. At the first shot, he is hugging Sandy on the left side but after seconds, he is on the right one.

#2. Glasses appear and disappear

Another mistake is discovered when Rizzo begins wearing her sunglasses as she is lying on the benches. However, when she pouches the girls aways, we can’t see her sunglasses anymore. In the next shot, her glasses are seen on her face.

#3. The red thread

In a scene where Sandy joins the cheerleading squad, keen-eyed viewers might spot a long, conspicuous red thread snaking through the lettering on her uniform. But, in the blink of an eye, as the next scene unfolds, the mysterious thread vanishes into thin air.

#4. The room cleans itself

A tiny error appears in this scene, do you notice it? Look at the bed’s headboard, you see it is messy and full of things, but in a blink of an eye, it is clean.

#5. Mattresses come and go

In the iconic "Greased Lightning" performance, the guys take the stage for their musical solos, showcasing their slick moves. During one memorable moment, Danny twirls around the car, and it becomes clear that there's nothing beneath but wheels. However, in the next shot, there are two white mattresses discreetly placed on the floor.

#6. Incomplete school uniform

Some viewers wonder why Danny’s uniform says Rydell High School, his school’s name while others’ just say Rydell. It could be a blunder because they are a team.

#7. The film crew is seen in the background

About an hour into the movie during the school dance contest, there's a noticeable error. You can spot the film crew sitting in the bleachers. While you might think they're just extras, their clothing and equipment don't quite match the Grease era, making for a funny and unintentional cameo by the production team.

#8. The cowboy

In the school dance contest, there's another noticeable mistake. The gymnasium's main decoration is a large cowboy, and during the dance, he breaks down and covers the floor with white paper. Oddly enough, in the previous shots, the cowboy is paper-free, leaving us with a noticeable continuity error.

#9. Danny’s sudden change of shoes

Let’s clearly see the scene where Danny and Sandy are dancing. Firstly,  Danny puts on formal shoes with heels but in the next shot, it switches into flat black sneakers.

#10. Color-changing pins

Rewatch the scene when Rizzo is talking with Sandy before her solo, you notice that Sandy’s barrette is pink but it switches into white afterward.

#11. Danny’s jacket with the wrong years

As Danny tries to impress Sandy and joins the school's track team, he wears a white jacket with two red lines on his arm at the end-of-year carnival. However, he should only have one red line, and this clothing mistake stands out in the film.

#12. Dirt magically disappears from clothes

During the iconic song "You're the One That I Want," there's a noticeable mistake. When Danny falls to the ground and then gets up, his black t-shirt is visibly dirty, and Sandy even puts her dirty shoe on him. However, a couple of shots later, his t-shirt appears miraculously clean again, indicating a continuity error in the film.
