Factual error: Lex crashes and his car lands on its roof, but in the span of a few seconds it has sunk straight to the bottom, and turned the right way up. Cars don't sink that quickly. (00:17:25)
Factual error: When the bug kid crashes his car, he's driving a VW Beetle, which has the motor in the rear, therefore would not have shut off in a head on collision.
Factual error: Lana says the theme of her mother's prom was Saturday Night Fever, but she was in the class of 1977. Prom would take place sometime before graduation (which would be in May, maybe June), likely February or March. Filming for "Saturday Night Fever" didn't even begin until March 1977.
Factual error: When Palmer is looking at the phone log, the wrong area codes are shown. Most of the list consist of the city of Topeka, with Wichita and Kansas City also seen, with a "206" area code. "206" serves the Seattle Washington area. The other area code seen is "620", which is a Kansas area code, but Topeka is in the "785" area code.
Factual error: When Ian throws the unconscious Chloe over the edge of the dam we see her falling down as Clark falls with her. However, Chloe's body position is unnatural for someone who is falling while unconscious. Her head/body is arched backwards when air resistance should have forced her body to become level/straight.
Factual error: Perry uses a simple black rope to tie himself to the railing by his ankle. This is not a bungee cord of any kind. He falls and is stopped, jerked to a stop actually, with both his weight and the weight of Clark pulling on his ankle. This would cause a very serious sprain if not an actual broken ankle yet Perry shows no signs of being injured when he and Clark walk to the bus.
Factual error: Tate fires at Clark, who is dressed as the drifter, 8-9 times from a revolver that is chambered for only 6 rounds.
Suggested correction: I count 5 shots fired, which is how he had 1 left that he was planning on using on himself. You must be counting ricochets or other sounds as shots fired.
Factual error: In the scene where Clark stops Pete on the country road and is trying to talk Pete out of racing, mountains can be seen in the distance. There are no mountains that tall in Kansas. (00:09:55)
Factual error: Clark lifts Chloe's car by the back. He is only holding on to the very back left portion of the car, yet while he's turning it, the car is completely horizontal. The front of the car would buckle since it weighs so much and isn't being handled by its center of gravity.
Factual error: There is a snow pattern on the Quicktime player after Chloe's message to Clark finishes. She would have recorded in on a camcorder, so there wouldn't be any snow pattern, it would be a blue or black screen. The only way there could have been is if she recorded it, put it on VHS, then copied it back onto a DV tape, then transferred it back onto her computer, but there's no reason for her to do this.
Factual error: When Lionel is leaving the prison, there is a bus unloading convicts as he walks past. No prison in the world would ever unload inmates and release an inmate in the same area at the same time.
Factual error: Alicia gives Clark the necklace with red kryptonite and this causes him to break Alicia's bracelet a few shots later. She then is able to teleport once it is removed. Now, according to the story, that bracelet prevents her from teleporting by releasing 'trace' amounts of lead into her bloodstream. If that were the case she would have to wait until the trace amounts were cleared from her system to start teleporting again.
Suggested correction: The way her powers work is unknown. Her body may be able to quickly remove trace amounts of lead from her body, which is why she would need to constantly have trace amounts put into her bloodstream.
Factual error: While Clark is standing on the field at Metropolis University at the end of the episode the shot pulls back to show the entire field. As it does there are two 50 yard lines visible and the goalposts in the wrong position because it's a Canadian football field, but Metropolis University is in Kansas.
Factual error: Clark finds Lois in the sewer and decides to use his heat vision to destroy the lock of the gate that is separating them. Clark uses his heat vision on the lock and the lock explodes, this is a very minor explosion. It also causes the door to fly off the hinges. Now the explosion from the lock is odd since heat vision causes things to melt and not explode, but Clark wasn't even using the heat vision on the hinges and they are destroyed. This is inconsistent with how his heat vision has been shown to work before.
Factual error: Clark huddles over Krypto to protect him from the blast of the exploding van. He does not cover Krypto's head before the blast of fire hits them yet Krypto shows no sign of damage. At the very least the fire should have singed his fur.
Factual error: In the 5th season episode "Lexmas," Chloe says she needs Clark to deliver the Daily Planet's Toys For Tots contribution because of a Teamsters' Strike. However, the Toys For Tots program is run by the United States Marine Corps Reserve, and collection and distribution is handled by Marines and Reserves. The Teamsters have nothing to do with it.
Factual error: The last scene is said to be set in "Iguazú Falls - Patagonia, Argentina." Iguazú Falls are nowhere near Patagonia. (00:40:00)
Factual error: When Clark is on the roof, and Lionel calls him over to walk to his car with him, in the background as they walk, you can see a building which has the logo of a Canadian bank. Although set in Smallville and Metropolis, Smallville is filmed in Vancouver.
Factual error: Chloe wants to access the security camera files on the Luthor mansion server to see what happened to Lex. She can't crack the password, so she says she'll just download the entire hard drive. She pulls out a thumb drive and proceeds to do so. Two big technical problems here. Firstly, if she can't log in, she can't access anything on the server. And Secondly, the entire hard drive for a server (which is huge) containing video files (which are huge) will not fit on any thumb drive.
Factual error: Lana is trying to find out what Lex is up to. She gets a hold of his briefcase and takes it to the mansion where she shoots the locks off the case. When she does the case jumps a little bit but this is far less than it should. She is shooting at it from less than a foot away. The force of the bullet should have sent that case sliding across the desk at that range. (00:15:35)
