The line comes from The Lord of the Rings The Two Towers, released in 2002 and directed by Peter Jackson. In the Golden Hall of Edoras, Saruman speaks through the weakened King Théoden to banish Gandalf, not realising Gandalf has returned stronger. The scene became a widely quoted moment from the trilogy, and the short clip later spread on soundboards and in edits as a reusable put-down for anyone overstepping, trying to give orders, or entering a space where they are not in charge.
