Quantum Leap (1989) - 81 mistakes in entire show

Continuity: The rearview mirror on Nick's car disappears and reappears repeatedly, when he pursues the laundry truck and later at the cabin.

Revealing: At Boston's FBI, Al's reflection is visible repeatedly, such as on the fire extinguisher's chrome surface in the hallway and on the elevator while Sam talks about the cabin.

Continuity: When Sam uses martial arts against the men from the van, one of them pulls a knife as he kneels on his right knee in the close-up, but next shot he is kneeling on his left knee.

Continuity: When one of the sicko men from the van pulls a knife on Sam, the white blouse is either tucked into the skirt or hangs over it, depending on the shot.

Revealing: When Sam and Al are in the station wagon pursuing the van, both Sam and Al's reflections are visible on the wagon's front hood. Al, as a hologram, shouldn't have one and Sam's reflection should be as Kevin's mom.

Revealing: When Sam and Al are walking and talking, just after Scooter (being chased by the dog) throws Sam the dean's prized basketball, Al's shadow is visible on the ground, though as a hologram he doesn't actually have one.

Audio problem: When Sam says "I'd rather be dead," his lips don't move in sync with the words.

Factual error: The Post Raisin Bran cereal box sitting on the Beckett family breakfast table in 1969 has a 1990s box design.

Audio problem: During the speech where Al tells Sam to quit (to force Chewie to play), Sam says he can't quit but his mouth doesn't move for a couple seconds after the words start playing.

Continuity: As Sam is preparing to go on stage as Don Quixote, after catching the lead actor, a quick cut to Dulcinea dancing is shown. It is supposed to be Sam's love interest and ex piano teacher Nicole as Dulcinea. However, you can see Nicole standing in the background, in the pink outfit she was wearing in scenes from the beginning of the episode.

Factual error: At the end, Sam reads a poem from a Mark Twain book and says, "Twain wrote it when his daughter died." But the poem, famous because it was engraved on the daughter's headstone, isn't by Twain, but by poet Robert Richardson. Twain never claimed authorship, so Sam couldn't be reading it with Twain's byline from any of his books.

Continuity: When Al is standing next to the juke box, Sam walks over to make a selection, and when Al starts talking his reflection is visible on the glass. Later in this episode, Sam is talking to Al at the sink of the dressing room at the ball park. As Sam looks into the mirror he says he thinks Al is a vampire, to which Al replies, "Neurological holograms don't reflect, Sam."

Continuity: Willis drops his cap on the road when he runs away. It's still there in the long shot of him running, but after the commercial break we return to the same scene, and as Sam stands up, the cap is no longer on the road behind him.

Continuity: The shaving cream smeared on Sam's face looks nothing at all like the cream on his reflection's (Tom's) face in the mirror.

Continuity: After throwing the laundry bags out the back of the truck, close up shots on Sam and the girl show the back of the truck being relatively empty. However, the next shot from the rear of the truck has the back full of laundry bags again.

Revealing: After Sam nearly falls down the elevator shaft, the scene fades and comes back in with Sam speaking to the landlord about the incident. The landlord brushes off Sam's hat with his hand and hands it to him. The brushing motion was played in reverse first to extend the length of the action.

Factual error: In the scene where the guy is telling Machiko about the major league teams that wanted him, he mentions the Indians, Yankees, and Orioles. The episode is set in 1953 and the story is from before World War II. While there had been a minor league team called the Orioles up to that point, there was no major league team called the Orioles until 1954.

Continuity: The mud stain Sam gets in his slide covers most of the front of his baseball jersey. But a few shots later, it becomes a much smaller streak on just the left side.

Factual error: When Sam knocks on Diana's door, she opens it. But we've just been told that she's completely deaf, so there's no way she could have heard him knocking.

Revealing: When Sam is putting the locket on her in the coffin, Hilla's "corpse" is breathing.
