Peter Stormare: Satan
John Constantine : They have the Spear of Destiny.
Satan : [mocking him] "They have the Spear of Destiny!"
[becomes serious, leans in]
Satan : Or is it another one of your cons?
John Constantine : Go look for yourself.
John Constantine : You've waited twenty years for me, Lu. What's another twenty seconds?
Satan : [his last lines] No. You will live, John Constantine. You will live so you will have the chance to prove that your soul truly belongs in hell. Oh, you will live. You will live.
[after Satan thwarts his son's plot]
Satan : So...
John Constantine : So.
Satan : Yeah, what do you want? An extension?
John Constantine : The sister, Isabel.
Satan : What about her?
John Constantine : Let her go home.
Satan : [sneers] You're willing to give up your life so she can go to Heaven?
[John nods. Lucifer shuts his eyes for a moment]
Satan : Fine. It's done.
Satan : Time to go, John.
John Constantine : Yeah.
[after Constantine slits his wrists and then tries to light up a cigarette]
Satan : You know, when you cut too deep, you cut the tendons. Finger movement goes out the window.
