Trivia: During the recording of Jor-El and Lara-El, Jor-El (played by Julian Sands) pronounces Krypton the same way Marlon Brando did, who played Jor-El in the 1978 "Superman" film. That is he says it more like "Kriptin."
Trivia: This episode bares some resemblance to the story of Captain Marvel, also known as Shazam. In it, young Alec Abrams magically turns into an adult, Steven Swift who is the superhero Angel Warrior. Stephen Swift is played by Carlo Marks. Marks appeared in season 7 as Chloe's fiancé in an alternate reality where Kal-El never came to Earth.
Trivia: Jerry Siegel, the co-creator of the Clark Kent/Superman character worked on a school magazine when he was at Glenville High School, Cleveland. The magazine was called The Torch - the same name of Smallville High's school magazine, edited by Chloe Sullivan and with Clark Kent as an on/off contributor.
Trivia: In the Episode "Flash" when Clark confronts the Flash in his hotel room, he reads off the fake I.D.'s Jay Garrick, Barry Allen and Wally West. Those are the secret identities of the first three men to be called the Flash. 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)
Trivia: Despite many hours of outdoor farm work, Clark never gets a tan or a sunburn. In fact, Tom Welling, who plays Clark, is contractually forbidden from getting a tan, because the show creators were not sure if Kryptonians could tan.
Trivia: Martha makes a remark suggesting she thinks Bridgette Crosby and Dr Swan are together to which Bridgette comments "In another lifetime." Bridgette is played by Margot Kidder, who played the original Lois Lane, Prof Swan was played by the late Christopher Reeve. A nice touch I think.
Trivia: Michael Rosenbaum is the only actor to play both an enemy and ally of Superman in two separate TV series at one time. In addition to playing Lex Luthor in "Smallville," he is also the voice of The Flash in the cartoon series "Justice League."
Trivia: The Smallville Torch that Lex views on the internet has two articles that refer to past episodes. Pete wrote an article about his trip in a limo called Take Yourself Out Of The Driver's Seat ("Hourglass") and Chloe reprinted The Most Controversial Speech Ever Given In Smallville by Lana's mother ("X-Ray"). (00:17:45)
Trivia: In the episode where Aquaman appears, he says, "We should start a JLA," (Junior Lifeguards Association). This is funny because he and Superman are later on a team Justice League of America.
Exodus (2) - S2-E23
Trivia: Throughout this episode, the Superman theme tune can be heard at various points being played very softly and slowly. The first time it is heard, it is only the first few opening keys, but the last time it is heard, it is fully played.
Trivia: Annette O'Toole who plays Clark Kent's mom also played the role of Lana Lang in the Superman III movie.
Trivia: In the episode where Clark is lured to the asylum when Lex is with some of his former enemies, Jonathan Taylor Thomas' character taunts Lex while holding a newspaper with a headline starting, "Themysciran princess" and some other words. That is a reference to Wonder Woman, who is from Themyscira.
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.
