Bound - S4-E9

Continuity mistake: After Clark saves Lex from the ring of fire we see the area that was burned by the fire. The candle that Shannon used to light the alcohol is no longer on the floor. Since the candle was in the fire it should be partially melted and there would be some evidence of it.

Red - S2-E4

Continuity mistake: During the opening scene, behind Jesse you can see the vice principal walk up behind her and reach out as he's about to put his hand on her shoulder, yet the very next shot of Lana, in the background you can see he's just exiting a room.

Redux - S2-E6

Revealing mistake: In the Talon when Crissy is talking to Clark, we see a close up of her hand aging. However, as her hand ages, a reflection of her real hand (which supposedly aged) can be seen on the metal clip of her clipboard, which is still young and smooth, and not aged.

Reaper - S1-E17

Revealing mistake: As Tyler slides across the floor, after Clark knocks him out of Whitney's father's room, he hits the camera. When he does the camera has a noticeable shake to it because of it.

Hothead - S1-E3

Continuity mistake: While Clark and Jonathan are talking about Clark being on the football team, Jonathan puts his hands on Clark's shoulders. Between shots, the position of Jonathan's hands on Clark's shoulders repeatedly changes.

Pilot - S1-E1

Plot hole: After Chloe shows Clark the Wall of Weird, Clark is confronted by Whitney outside. Whitney is wearing Lana's meteor rock (kryptonite) necklace but Clark actually feels no effects until he ends up opening Whitney's shirt.

X-Ray - S1-E4

Revealing mistake: While Lana is listening to her Mother's graduation speech she reaches up to her neck for her meteor rock necklace. Her hands do not reach far enough back to unclasp the necklace yet the necklace comes off anyway.

Obsession - S3-E14

Continuity mistake: As Alicia holds the kryptonite on Clark her hand turns between shots. While she says ".but you broke the rules first." there is a camera change. Before the change the frontal view of Alicia has her holding the kryptonite with the glowing part straight up. After the camera change she is now holding it so it points to her left.

Fever - S2-E16

Continuity mistake: The position of Clark's sleeve to the tourniquet change between shots. When Dr. Bryce first ties the tourniquet she does so at about an inch from the end of the sleeve. In the next shot, as Clark lies unconscious and nobody touches his sleeve, the tourniquet is tied around the sleeve and no longer on his skin. Just before Dr. Bryce sticks the needle in it's back to being an inch from his sleeve.

Vessel - S5-E22

Continuity mistake: In Episode 22- Season 5 - "Vessel": At the start, Lex wakes up and heads towards an open field many miles away from the mansion. They show a camera shot of his face in the field and the sky is grey and cloudy, but in the very next shot the sky has turned blue and the sun is shining.

Vessel - S5-E22

Visible crew/equipment: Episode 22, Season 5 - "Vessel": Lex returns to the mansion, after being abducted, with his new powers. When he shows Lana by shooting his hand, they start talking by the stained glass window. The reflections in their eyes are supposed to be the light coming through the window, but are actually from a white screen used for lighting. The reflections in their eyes are rectangular to confirm this.

Lucy - S4-E16

Plot hole: In episode 4-16: "Lucy," there is no reason for the criminals to be chasing Lucy on the ski slopes at the beginning of the episode. We learn later that she's been working with them all along; she calls Lois during the chase, and the call is part of Lucy's plan with the criminals. Lucy being chased by the criminals would make sense given the story she gives Clark during the next part of the episode, but it doesn't make sense for what we ultimately learn is the truth. And nobody from Smallville is anywhere near the ski chase, so it also doesn't make sense as any kind of a ruse.


Krypto - S4-E14

Other mistake: In episode 4-14: "Krypto," Genevieve tells Jason that the heirs of a 17th century woman named Gertrude are in danger. She then tells him that they themselves are "Gertrude's ancestors." But she must mean descendants, which means the opposite of ancestors.


Jitters - S1-E8

Revealing mistake: In the early scene with the baby, there are a few overhead shots of the parents and child. It is clear that in these shots a fake baby was used - he is completely motionless, even though he was moving arms and legs before and after and is crying.

Pilot - S1-E1

Continuity mistake: The hole in the guard rail changes size and shape between the shot of Lex driving off it and another looking up at it from below.

Metamorphosis - S1-E2

Continuity mistake: After Greg hits Clark with the pipe in the foundry, Clark's hands are very dirty. In the closeup on Clark's hand immediately after he lands, the hand is clean to show the effects of the Kryptonite.


Crush - S1-E19

Other mistake: When Justin launches the chainsaw towards Chloe, Clark steps in and it breaks upon hitting his chest. However, there is no damage at all done to his clothes. There should have been at least a tear in his shirt. He's not wearing Super-Plaid.


Tomb - S5-E14

Character mistake: While Clark and Chloe are at Daily Planet, Clark asks her what is wrong with her mother. Chloe responds that her mother left when she was twelve years old. In the episode Lineage, Chloe and Clark are looking for Rachael Dunleavy and Chloe says her mother left when she was five.

Reckoning - S5-E12

Continuity mistake: Clark and Martha show up at the barn. The interior rear view mirror is missing when looking out from inside the car, but it is there when looking in the car from outside.

Phantom - S6-E22

Continuity mistake: When Clark hacks into Phillipe's police report, there is a photo of Phillipe facing sideways. In the next shot the photo has changed, so that now he is facing forward.
