Remember those letters of transit, the ones Ugarte (Peter Lorre) says "cannot be rescinded, not even questioned" because they're signed by Charles de Gaulle? Actually, de Gaulle was in London leading a government in exile in December 1941, when "Casablanca" takes place. His signature would have carried no weight in Morocco under the Vichy regime, which had already tried him in absentia and condemned him to death for treason.
It makes sense that Reggie (Audrey Hepburn) is freaked out by Scobie's metal claw. But when the villain uses his artificial hand to hold a gun on Reggie's protector (Cary Grant), there's no way he could pull the trigger.
Dirty Dancing (1987)
Her lingerie is the giveaway. When Baby, aka Jennifer Grey, gets ready for summer of 1963's end-of-season dance, she's wearing an '80s-style no-seam bra. And although she puts on old-fashioned stockings, she's wearing contemporary pantyhose—and a backless dress that shows no bra—in that final scene.
The Ten Commandments (1956)
Even for an infant who would grow up to collaborate with God in parting the Red Sea, a diaper with safety pins—visible when baby Moses drifts down the Nile—seems like an unlikely miracle for 1393 B.C. Then again, you can also see a zipper in the back of Bithiah's dress.
Pulp Fiction (1994)
The heart isn't located under the breastbone, paramedics treat a heroin overdose with Narcan, not adrenaline, and the patient gradually wakes up rather than bolting upright the way Mia Wallace (Uma Thurman) does in "Pulp Fiction." But the scene is so compelling, why quibble? Still, it's strange how the red Magic Marker dot that Vincent (John Travolta) puts on Mia's chest as a bull's eye disappears when she regains consciousness.
North by Northwest (1959)
One of the most famous movie mistakes ever: When Eve (Eva Marie Saint) pulls a gun on Roger Thornhill (Cary Grant) in the Mount Rushmore restaurant, a boy in the background covers his ears because he knows what's coming. And by the way, there's no such thing as a "north by northwest" compass point.
"I'll tell you what the trouble is, you see, I'm a southpaw," Rocky (Sylvester Stallone) tells Adrian (Talia Shire) on their first date. In other words, the Italian Stallion has a left-handed boxing stance. So why does he have a conventional right-handed stance when he's duking it out with carcasses in the meat-packing plant?
Double Indemnity (1944)
In this classic film noir, Fred MacMurray plays a bachelor insurance salesman who falls for a seductive housewife (Barbara Stanwyck) and joins her in a plot to kill her husband. Of course, the plan goes awry. But even before that, something's amiss: MacMurray wears a wedding ring (his own) throughout the movie.
Django Unchained (2012)
Cool shades. According to the movie's costume designer, they were inspired by a pair worn by Charles Bronson in 1977's "The White Buffalo." Just one problem: "Django" takes place before the Civil War and sunglasses weren't introduced in the U.S. until the 20th century.
Gone With the Wind (1939)
After Ashley (Leslie Howard) returns wounded from a nighttime raid—and Rhett (Clark Gable) saves him and his pals from being arrested by telling the Yankees that they all spent the evening at Belle's whorehouse—Melanie (Olivia de Havilland) picks up an "oil lamp" with an electrical cord conspicuously attached.
Raiders of the Lost Ark (1981)
Thinking his beloved Marion has been killed, Indiana Jones (Harrison Ford) drowns his sorrows at this outdoor bar in 1930s Cairo. He's so distraught that he's oblivious of the crew member who makes an unplanned appearance—in '80s-style jeans and a T-shirt—just over Indy's right shoulder.
Apocalypse Now (1979)
Although dates aren't specified, the soundtrack (starting with the Doors' "The End") suggests that the action takes place in the '60s, and a newspaper clipping about the Manson murders narrows it down to August 1969. But Playboy centerfolds posted by soldiers are from the mid-'70s—perhaps in honor of 1974 Playmate of the Year Cynthia Wood, who takes center stage in the film's USO show.
Rebel Without a Cause (1955)
"There's no sticking … just a little jabbing," Buzz tells Jim (James Dean), outlining the rules of their switchblade face-off outside the Griffith Observatory. But even "jabbing" draws blood—which keeps appearing and disappearing on Jim's shirt throughout the fight.
When Maximus (Russell Crowe) takes part in a loose reenactment of the Battle of Carthage in the Coliseum, a chariot smashes into a wall and flips over. At that moment, you can see a gas canister in the rear of the vehicle.
Some Like It Hot (1959)
One of the hottest scenes in this Billy Wilder classic, which is set toward the end of the Jazz Age, is Marilyn Monroe singing "I'm Thru With Love." Never mind that this jazz-pop standard was written later, at the beginning of the Great Depression.
Early in the movie, Kate Winslet's beauty mark moves from one side of her face to the other. Later Jack (Leonardo DiCaprio) recalls ice fishing with his dad on Lake Wissota. This is surprising, given that Lake Wissota was formed when a power company built a dam on the Chippewa River in 1918, six years after Titanic went down.
Taxi Driver (1976)
Celebrated for its gritty realism, Martin Scorsese's masterpiece begins with a false note—a taxi dispatcher interviewing Travis Bickle (Robert De Niro) and grilling him about why he wants to drive a cab. Let's just say it's a question no New York City dispatcher has ever asked a job applicant.
Breakfast at Tiffany's (1961)
Orangey, the marmalade tabby who appears as Cat, Holly Golightly's generically named pet, went on to supporting roles on "My Favorite Martian" and "The Beverly Hillbillies." But in "Breakfast at Tiffany's" he had considerable help. Nine cats shared the screen with Audrey Hepburn, all playing the same role, and one of them looked strikingly different from Orangey.
The Godfather (1972)
In later years, it became known as a "Moe Greene Special"—a character being killed with a single shot to the eye. In "The Godfather," the scene is so gruesome that you might not have noticed that the lens of Moe's glasses cracks, but there's no bullet hole.
Krakatoa, East of Java (1969)
Krakatoa is west of Java.
