Alfred Hitchcock introduced the term 'MacGuffin' to describe a plot device or object that pushes the narrative forward. It can be anything that sets events into motion or keeps them on track. In Hitchcock’s films, an example is the birds in The Birds, or Norman Bates’s mother in Psycho, which drive the plot's momentum.
Although Hitchcock coined the term, he wasn't the only filmmaker to use MacGuffins. These intriguing plot devices have been part of storytelling for centuries, especially in classic works of fiction. Here’s a look at the 10 most memorable MacGuffins from some of the best films ever made.
Spoiler Alert: We will reveal some major plot points in these films. If you haven’t seen them yet, proceed with caution. Particularly with the first entry about Citizen Kane — we discuss the movie's ending. Consider this your warning.
10. Doug – The Hangover

A lot of viewers may forget that the main characters end up in quite a bit of trouble during their wild hangovers, all stemming from their desperate search for Doug, who was the reason they traveled to Vegas in the first place.
Doug was about to marry, and they were throwing him a classic bachelor party. Though Doug's role in the film is brief, appearing only at the start and again at the very end, his presence is key to the story.
At its core, the movie is all about finding Doug. The unexpected tiger and the overwhelming confusion about what transpired the previous night served as the hilarious extra layer to the chaos of The Hangover.
While some MacGuffins are blatantly obvious throughout a story, Doug is a prime example of a MacGuffin who is hardly ever seen on screen but drives the entire narrative.
9. The Death Star Plans - Star Wars

Thanks to Rogue One, we finally learn the backstory behind how the Rebels managed to obtain the plans for the Death Star. (As an interesting note, Rogue One also featured the plans as its own MacGuffin.) In the original Star Wars, however, the plans were central to driving the plot forward.
Once the Tantive IV is boarded and we hear that "the Death Star plans are not in the main computer," the Empire relentlessly pursues them. The stormtroopers chase R2-D2 and C-3PO to Tatooine, where they destroy Luke’s uncle and aunt's home in their search for the plans.
This leads to the introduction of Han and Chewie, as the plans travel across space and eventually reach the Rebel Alliance, where they are analyzed to identify a possible weak point.
Here’s why the plans are the ultimate MacGuffin: Had Vader located them on the ship during the opening sequence, the plot would have ended right there. He'd have captured Princess Leia and proceeded to destroy the Rebel Alliance, effectively sealing their fate with the secret of their vulnerability kept out of the enemy's reach.
8. The Briefcase - Pulp Fiction

Here’s the interesting part about MacGuffins: Their true nature isn’t always revealed. On-screen characters typically need to figure out what they are to keep the story moving. But when it comes down to it, do we, as the audience, really need to know what’s inside the briefcase everyone’s so fixated on in Pulp Fiction?
The quick answer? Not at all. It’s irrelevant. What matters to us as viewers is that whatever is in that briefcase holds great significance.
For years, speculation has swirled around the contents of the mysterious briefcase. Fan theories have suggested it could contain anything from the stash of diamonds stolen in Reservoir Dogs, to Rudolph’s glowing nose, O.J.’s missing glove, the Oscar Quentin Tarantino wished to win, or even the soul of Marsellus Wallace (which some believe explains the Band-Aid on the back of his neck before he reclaimed it).
Tarantino himself has confessed that there is no definitive answer to what’s in the briefcase. He intentionally crafted it as a MacGuffin to add intrigue to the story without offering any concrete explanation.
7. The Genesis Device – Star Trek II and Star Trek III

Though the main tension in Star Trek II: The Wrath of Khan and Star Trek III: The Search for Spock seems to revolve around the personal vendetta between Khan and Kirk, along with the animosity Kirk has for the Klingons, the true driving force behind the plot is the Genesis Device.
Initially intended to create life, the Genesis Device was feared outside of Starfleet as a weapon of mass destruction, capable of wiping out entire planets and eradicating all life forms—at least, those that existed before its activation.
The Genesis Device is what ultimately leads to Kirk’s reunion with his son. Later, when the device aids in saving Kirk’s life, it becomes the target of the Klingons, who, driven by vengeance, kill Kirk’s son.
Spock’s body eventually reaches the Genesis planet, where the extraordinary science of the device revives him. This sparks the crew of the Enterprise to make an unlawful journey, taking their ship in pursuit of rescuing their fallen—and now resurrected—friend. Among MacGuffins, the Genesis Device stands out as one of the most captivating.
6. Private Ryan – Saving Private Ryan

Though many people have been used as MacGuffins, few are as crucial as Private James Francis Ryan in the film bearing his rescue as its focus. The true heart of Saving Private Ryan isn’t the Nazis or Operation Overlord, but rather the perilous mission of Tom Hanks and his team of Rangers, tasked with saving the titular private from certain death.
To be fair, Ryan does have a crucial role in the storyline. However, when he is found, his actions represent another part of the MacGuffin mechanism that ultimately leads to the tear-jerking conclusion. His decision to remain with his unit instead of retreating with the Rangers results in the deaths of several of his comrades.
The narrative comes full circle when we meet the elderly man in the cemetery, now revealed to be Ryan. He asks his wife if he was a good man and if he lived a fulfilling life. Even as the MacGuffin of the tale, Ryan understands that his decisions were central in driving the plot forward.
5. The One Ring – The Lord of the Rings

When it comes to a powerful artifact acting as a MacGuffin, one need look no further than the One Ring. Not only is this the ring that Sauron desperately seeks to reclaim throughout the series (both film trilogies and all the books), but it also possesses immense power in its own right. We discover that it is not merely the most powerful ring, but the one that unites all others.
“One ring to rule them all, One ring to find them, One ring to bring them all and in the darkness bind them.”
The Fellowship of the Ring sets out on an epic quest to take the ring back to Mount Doom so that it can be destroyed. This journey is only the beginning of a much larger adventure that affects the lives of every creature in Middle-earth.
While The Hobbit doesn’t explore the full backstory or power of the Ring, Peter Jackson’s Hobbit trilogy introduces it into the narrative. However, in The Hobbit, the true MacGuffin is the treasure—and more specifically, the Arkenstone, the gem Smaug delights in resting upon.
4. The Holy Grail – Indiana Jones and the Last Crusade

We could have used anything from the Ark of the Covenant to those ridiculous crystal skulls because the treasure of any Indiana Jones film is, by definition, a MacGuffin. We decided to go with the Holy Grail from Indiana Jones and the Last Crusade because it is the ultimate MacGuffin for any treasure hunter. This is probably the easiest example of a MacGuffin in film as it is specifically stated as the goal of everyone in the film.
First, we find that Indy’s father was looking for it. Then we learn that Adolf Hitler and the Nazis are looking for it. Finally, we have Indiana Jones looking for it. But in actuality, he was only looking for his father. He wouldn’t have needed to look for his old man were it not for the quest for the Holy Grail.
When it is finally found and has served its purpose, it is even cast aside or thrown away, albeit accidentally at first. When a MacGuffin serves its purpose to drive the story, it doesn’t matter anymore if it “lives or dies,” only that it existed at all in the first place.
3. RosebudCitizen Kane

Citizen Kane opens with the death of Charles Foster Kane. He is holding a snow globe that drops to the floor just after he utters his dying word, “Rosebud.” The meaning of the word is the true MacGuffin in the film because it sets Jerry Thompson with the task of learning who or what Rosebud was.
What could this disturbingly wealthy man have meant with his dying breath? It’s the drive to learn what it means that makes “Rosebud” the greatest movie MacGuffin of them all.
The entire film revolves around Thompson’s quest to learn the meaning of the word. But in the end, he never does. Only the audience knows the meaning of the term when the camera pans around the room at Xanadu to reveal the trade name of the sled: Rosebud.
The sled is what an eight-year-old Kane was playing with the day he was taken from his home in Colorado. It is considered to be junk and is burned, leaving the question and MacGuffin forever unanswered within the confines of the film.
2. Letters Of TransitCasablanca

The movie Casablanca is not just famous for its iconic lines, but it also stands as one of the earliest examples of a MacGuffin that goes unnoticed by the audience. While the central focus is the love story between Humphrey Bogart’s Rick Blaine and Ingrid Bergman’s Ilsa Lund, the true object of importance for the characters is the letters of transit.
Rick’s main goal throughout the movie is to ensure the safety of his former lover. In the end, he sends her off on a plane, securing the letters of transit that allow them to escape Nazi-occupied Morocco.
The letters were acquired through the murder of two German couriers, which elevates their significance. Yet, the audience is far more drawn to the love story between Rick and Ilsa than the MacGuffin itself, making the letters of transit one of the most masterful plot devices ever.
1. The Maltese FalconThe Maltese Falcon

Films from the era when Hitchcock coined the term 'MacGuffin' feature some of the most notable examples, and The Maltese Falcon stands out with its iconic Maltese Falcon. In this film, the Falcon becomes the object of everyone’s desire, driving the entire cast’s actions. However, it’s not just the Falcon itself that serves as the MacGuffin—the search for it also propels the plot forward.
When Gutman and Cairo discover that the Falcon is a fake, they don’t seem upset or enraged. Instead, they feel a sense of excitement at the possibility of continuing their pursuit of the real Falcon.
The thrill lies in the pursuit—the global quest for the Falcon—which gives their lives a sense of purpose. The mere idea that they can continue chasing after it is enough to bring joy to the characters.
What makes the Maltese Falcon so fascinating is that its value is entirely derived from the fact that the characters in both the book and film want it so desperately. The implied value it holds is what defines it as a perfect MacGuffin, much like the briefcase in Pulp Fiction.
