Quantum Leap ( 1989 )

Plot hole: Sam wallops both kidnappers and rescues the son. They then leave the two child molesters unconscious beside their van. No one calls the police or has them arrested, so they're free to kidnap another kid. Sam doesn't leap until after an epilogue in which the loose ends are supposed to be resolved - but this question is left unanswered. It's not excused by a "just because we didn't see it happen doesn't mean it didn't" defense. The viewers shouldn't be left with a dangling plot hole, and one line could have cured this one.

Revealing mistake: 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.

Visible crew/equipment: After going to get pizza, Sam and the kids return home. As they pull in the driveway a long boom mike is visible in the back car window.

Continuity mistake: 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 mistake: 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.

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 mistake: When Sam and Ruben are fighting in the locker room they knock over a set of lockers (and only one set) and the door flies open on it. When they roll over the set of lockers the camera cuts and 2 sets of lockers are suddenly knocked down with all locker doors closed.

Continuity mistake: In the fight between Sam and Ruben in the locker room, Ruben has a white visor in his hands during the fight which magically disappears during the fight after a camera cut, and Ruben leaves after the coach breaks up the fight, without the visor.

Continuity mistake: Chewie is wearing the number 86 jersey in both games. However, when he is sitting out with his supposedly injured knee we see a shot of the number 86 jersey chasing an opponent.

Continuity mistake: In the party after the 1st game when Chewie and Sam are talking about the championship, Chewie pulls up a chair and sits on it backwards with his hands in his lap. After the cut to another camera, his arms are up on the back of the chair.

Continuity mistake: In one play during the montage sequence of the championship game, the quarterback for the Jaguars (Sam) is number 15 - but he wears 12 throughout the rest of the show. This is Sam, because Al later tells him to quit, so he's been playing the whole game.

Continuity mistake: The FBI agent's car is riddled with bullets in the opening scene. A few shots later, the same car rounds a corner during the chase, and all the bullet holes have disappeared. (00:03:30)

Factual error: When they arrive at the Federal Building, an exterior shot shows a green Karmann Ghia exiting with California license plate 1MMW713, except 1XXX plates first were issued in 1980. A blue California plate for the time should have been just XXX. (00:06:20)

Factual error: Sam is wearing a Casio calculator watch, which we are shown up close when he is driving the laundry van. The first calculator watch was made by Pulsar in 1975, and Casio's first calculator watch was released in the 1980s, long after this episode's 1973 date. (00:15:25)

Revealing mistake: When driving to the cabin, the mileage markers on the roadside indicate they are in Los Angeles, nowhere near Boston or Baltimore. (00:20:30)

Revealing mistake: When Al is helping Sam find Dana in the forest, his feet keep kicking up or moving the dirt and leaves, which a hologram shouldn't be doing. (00:39:00)

Continuity mistake: 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.

Audio problem: When the two bad guys are chasing the girl through the dark forest, one says "it's too dark," the girl screams, and the other says, "who needs light?" - but both say these without moving their lips.

Continuity mistake: After the bad guys attack the laundry truck and the girl starts throwing bags out of the truck, one sees in the close up shot a bullet-ridden gray door, but in the wide angle shot it's a pristine brown door.

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