The eye brows of the guard who tries to keep Lois off the Kaznian ship change from black to blond throughout the scene.
Lois Lane: (Looking at a video of Superman as he flys away after saving an airplane and refering to the S logo on his costume) Nice S.
Clark: Excuse me?
Clark: Now that the terrorists have your prototype, the Pentagon is undoubtedly gonna want you to build a bigger and better version for them. When all is said and done, this could net you a multimillion dollar windfall.
Lex: Lois, it almost sounds as if your friend here is suggesting I should be glad that my suit was stolen. You're very amusing Mr.... Kent, is it? Yes, I'll remember that.
Martha: I don't want anyone thinking you're like that nut in Gotham City.
Superman: (to Corben) Shall we go a few rounds without the suit?
This episode along "The Last Son Of Krypton, Parts 1 & 2" was released on DVD as Superman: The Last Son Of Krypton.
When this episode is rerun on Toon Disney, the part where Lois says "Nice S" has the word S muted.
Kaznia, mentioned here, is also mentioned several times in the series Justice League Unlimited, in which Superman plays a key role.
As in the movie, Lois gets the first exclusive on Superman. (In the comics, Clark uses the Superman story to get his job at the Planet).
Bibbo (B. Bibbowski) is introduced in this episode.
Lois used to date Lex, and dumped him.
At the docks, a burly man in a captain's hat is seen. The sailor has one eye squinched--a reference to Pop-Eye the Sailorman.
Lois: He is the Nietzschean fantasy ideal all wrapped up in a red cape. The Superman.
Friedrich Wilhelm Nietzsche (1844-10-15 – 1900-08-25) was a German philosopher. One of the concepts in his philosophy is the Übermensch, which is frequently translated to Superman.
When Martha Kent says "I don't want anyone thinking you're like that nut in Gotham City" she is obviously referring to Batman.
