Avengers: Infinity War

— Did you do it?
— Yes.
— What did it cost?
— ... Everything.

— I'm gonna ask you this one time, where is Gamora?
— Yeah, I'll do you one better, who is Gamora?
— I'll do you one better, why is Gamora?

— You're from Earth?
— I'm not from Earth, I'm from Missouri.
— Yeah, that's on Earth, dipshit!

The hardest choices require the strongest will.

— If I might interject. If you're going to Earth, you might want a guide. I do have a bit of experience in that area.
— If you consider failure experience.
— I consider experience experience. Almighty Thanos... I, Loki, prince of Asgard... Odinson... the rightful king of the Jotunheim... god of mischief... do hereby pledge to you... my undying fidelity.
[Thanos Uses the Gauntlet to stop Loki attempting to stab him in the neck]
— Undying? You should chose your words more carefully.
[Loki, as Thanos strangles him to death]
— You... will never be... a god
— No resurrections this time.

— Attachment to the material is detachment from the spiritual.
— I'll tell the guys at the deli. Maybe they'll make you a metaphysical ham and rye.
— Wait, wait, wait. I think I have two hundred.
— Dollars?
— Rupees.
— Which is?
— A... buck and a half.

— Stark!
— You know me?
— You're not the only one cursed with knowledge.
— My only curse is you.

— I like your plan. Except, it sucks. So let me do the plan and that way it might be really good.
— Tell him about the dance-off to save the Universe.
— What dance-off?
— It's not a thing.
