Other mistake: When Ryan gets hit by Martha's car, you can see he has both shoes on as he's going to the ground, and we never see a shoe flying through the air during the hit. Then James and Debra find the shoe in the middle of the street as they watch Martha drive off.

2 other mistakes in season 1 - chronological order
Other mistake: Lois digs up Chloe's grave site to unearth her casket. It is obvious that the casket is not buried six feet deep. You would think, with all that is going on, that LuthorCorp would have at least buried the casket deeper to deter inquisitive eyes and maybe throw in a few scattered bones for good measure.
Jonathan Kent: Are you okay?
Clark Kent: Can I answer that in about five years?
Jonathan Kent: Yeah.
Clark Kent: Dad I'm glad you and mom are the ones that found me.
Jonathan Kent: We didn't find you, Clark, you found us.
Trivia: When Clark confronts the Flash in his hotel room, he reads off the fake IDs Jay Garrick, Barry Allen and Wally West. Those are the secret identities of the first three men to be called the Flash in the comics. Also, this Flash says his name is Bart, like Bart Allen, the teen hero formerly known as Impulse and currently being called "Kid Flash." (00:10:35)
Question: Throughout the series, people mutate fairly soon after their exposure to kryptonite. Is it ever explained how Lana has managed to wear a piece of kryptonite around her neck for 12 years and not change?
Answer: The kryptonite only creates mutations when it reacts with the environment and an individual. Remember, the FDA and several environmental groups did check out Smallville after the meteor shower, but found no danger in the rocks. Obviously they're not always emitting mutating rays, or all the flora and fauna of the surrounding area would be horribly mutated.
