In "Exodus"
This is the first time characters Pete and Lionel meet on-screen - a scene possibly well overdue given how Lionel "ruined" the Ross family's creamed-corn business.
Besides the world domination part, most of Jor-El's speech to Clark about who he is was taken from the first Superman movie.
Did you know that Marlon Brando (Jor-El) was paid 4,000,000 for his small part in the movie and he did not memorize his lines! His lines were on the diaper of the baby in the movie!
