Baron Harkonnen: I will have Arrakis back for myself! He who controls the Spice controls the universe and what Piter did not tell you is we have control of someone who is very close, very close, to Duke Leto! This person, this traitor, will be worth more to us than ten legions of Sardaukar!
Feyd-Rautha: And who is this, traitor?
Baron

Harkonnen: I won't tell you who the traitor is, or when we'll attack. However, the Duke will die before these eyes and he'll know, he'll know, that it is I, Baron Vladimir Harkonnen, who encompasses his doom!

Duke Leto Atreides: I remember. Conceived in love, at a time of parting. Arrakis is a hostile world.
Lady Jessica: I must be sure you want this. It has to be

Duke Leto Atreides: And I whispered 'Yes'.
Lady Jessica: And I whispered 'I love you'.
