First question: is a special effects question: How did the sfx crew get the hoolah-hoop type restraining system to remain in perpetual motion that caged the 3 super-villains in the beginning of the movie ( Zod, Ursa & Non)? Where the hoops animated in ? Was it a practical effect, shot in-camera? Second Question: When Kal-El first encounters Jor-El in the fortress of solitude, Jor-El says, "Come with me now my son, as we break thru the earthly boundaries of your system, and travel thru time and space..." Did Jor-El open up some kind of warp system that transported superman to another time/galaxy? A "worm-hole" ? Because when the speech was over, he had aged 18 years. Did Kal-El go somewhere and return 18 years older?
