Clark looks through the wall of an aging theater which is about to be torn down. The wall itself has a door, above which appears "Enterance" (sic). Surely on a fancy theater with amazing baroque gold leaf interior decorations, shown later, such an obvious misspelling of "Entrance" would not have been tolerated.
When Clark flies for the first time to go see his parents in Smallville, he is wearing a maroon shirt. When he lands in Smallville he's wearing a blue denim shirt. But in the next scene at the dinner table, he's wearing maroon again.
In all other Superman series, Clark uses his glasses to hide his secret identity. However, in Lois & Clark: The New Adventures of Superman, Clark wore his glasses prior to being Superman without having any reason for wearing them. This may be in deference to the comic version of Clark, who was at one point wearing glasses made out of a material salvaged from his starship, which was the only thing that was able to withstand his heat and x-ray vision.
Clark's mother sews his suit together from normal earthly fabric, using her sewing machine and scissors. Only the "S" logo on the superman suit's chest is from Clark's home world, carried to earth along with his alien baby blanket. Yet in the rest of the episode and series, his suit is inexplicably as impervious to fire, bullets, and other hazards as Superman is.
