Independence Day, Will Smith's character (I don't remember his name) talking to the dead alien he's dragging along behind him.
This ins't a single quote, but a conversation:
"Forgive me, Your Highness! I did not see you!"
"Your aim would suggest otherwise."
"And, for that, I know I must die."
"Oh, then...then speak of this to no one and I shall be lenient."
