Zod - S6-E1

Visible crew/equipment: Martha and Lionel are in the barn when everything starts to fall apart. The camera shot changes from them to a boat falling from the rafters. As it falls there is a visible production crewmember hiding next to the window, holding a hay bale.

Phantom - S6-E22

Continuity mistake: When the Phantom child kills the doctor and drags him over to the fingerprint scanner to open the door, we see the doctor has no glove on his hand when it is placed on the scanner. But when his arm drops to the floor, there is a glove on his hand now.

Crimson - S6-E13

Other mistake: Lex picks up a chisel and stabs Clark in the side. It bounces off and out of Lex's hand. The last couple inches are bent and twisted. Chisels are made from extremely tough steel. But no matter how hard Clark is, Lex is not strong enough to exert the force necessary to bend the chisel itself.

Zod - S6-E1

Continuity mistake: In the scene between Martha and Clark near the end of the episode, the cut on Martha's forehead switches from above her right eyebrow to her left, and then back again.

Lockdown - S5-E11

Continuity mistake: Lex's aide is shot in the back as he makes a run for the door. When he goes down he slides head first almost all the way to the door. A few moments later, just as Flynn shoots out the security camera, in the security monitor image Lex's aide is now in a different position.

Crusade - S4-E1

Revealing mistake: Kristin Kreuk's body double in the shower scene is noticeable. She is slightly larger and differently shaped.

Spirit - S4-E18

Continuity mistake: Jonathan reveals the kryptonite to Clark/Dawn and Clark starts to react to it. Because of the kryptonite Clark drops the tiara he took from Chloe and it hits the floor near Chloe's hand. Then, just before Dawn is forced out of Clark's body, the tiara has slid several feet away and is now close to the furnace. Clark turns his attention to Chloe, she is faking an injury at this point, but now the tiara has moved back to be near her hand.

Spirit - S4-E18

Audio problem: As the band is playing right before Clark and Lois enter the prom, the drums are not synced with the music.

Spirit - S4-E18

Continuity mistake: As Clark/Dawn goes to hit Chloe, at first the camera is behind Clark and he swings as if he is going to slap her face. The next shot, as the camera is to their side, Clark's swing changes so that he shoves her across the room.

Onyx - S4-E17

Continuity mistake: In the barn loft evil Lex has a kryptonite ring in a lead box. When the camera is in front of Lex he is holding the box so that the lid is pointed towards his thumb. When the camera is behind Lex the box is turned so that the lid is pointed towards the end of his fingers.

Spirit - S4-E18

Plot hole: Clark is possessed by Dawn. Jonathan shows up and he has a chunk of kryptonite. Jonathan hides the kryptonite behind his back and Clark's body does not feel it until Jonathan takes the kryptonite out from behind his back. What, is Jonathon made of lead or something?

Shimmer - S1-E10

Continuity mistake: At the beginning, when Seth picks up the barbell to beat Troy with, Troy is at the end of the locker room with the showers. As Pete and Clark show up, Troy is at the other end of the locker room.

Recruit - S4-E13

Continuity mistake: As Clark and Geoff are driving, the first shot of the SUV as it comes around the corner shows the ground is wet and the wipers are going. During their conversation the windows are constantly being rained on. Geoff points to the stadium and they arrive a few minutes later and as they drive into the garage you can see the street is dry.

Pariah - S4-E12

Audio problem: Clark is upset over the death of Alicia and is in the barn loft bouncing a ball off the wall. His parents come up and Jonathan sits next to him and tells him that what happened was not Clark's fault. The very next shot shows Martha sitting down and you hear Clark throw the ball again but you can see that his hands never make and motion to correspond with that action.

Krypto - S4-E14

Continuity mistake: When Chloe pulls up to Clark's house there are patches of snow everywhere. While Clark hears the dog crash through the fence the fields are visible through the screen door and there is no snow on the ground at all.

Truth - S3-E18

Continuity mistake: As Lana says "I was thinking the same thing but we don't seem to be very good at it." there is a camera change as she says "but". Before the change she only has the red cup on the tray but after the change, even though she didn't pick it up, she has a red and a yellow cup on the tray. The other cup was on the table and jumps to the tray between shots.

Truth - S3-E18

Continuity mistake: When Chloe crashes through the bridge rails her windshield is dotted with raindrops. Just a few seconds later the blue truck hits her car from behind and now her windshield is dry.

Velocity - S3-E13

Continuity mistake: After Dante says "...if you want to turn that tortoise into a hare just give me a call." he walks off and the shot follows him as he walks all the way over to a black car and starts to work on it. The shot returns to Clark and Pete and Dante is shown walking away again on the left side of the screen.

Visage - S2-E11

Continuity mistake: In the shot where Clark picks up Lex's cue stick, the balls on the table are spread out in an arch consisting of 4 balls. The shot switches to a low level shot looking at Lex and the balls at Lex's end, where the arch should be, are no longer forming an arch.

Ryan - S2-E8

Continuity mistake: Nell meets up with Lana to talk to her about moving to Metropolis. We see Lana going up to Nell while riding a horse. She then stops and is about to dismount when they cut to another angle but now Lana is dismounting yet again.
