Here's the excerpt from "The Waste Land" that Theodore recites in the movie:
"_April is the cruellest month, breeding_
_Lilacs out of the dead land, mixing_
_Memory and desire, stirring_
_Dull roots with spring rain._
_Winter kept us warm, covering_
_Earth in forgetful snow, feeding_
_A little life with dried tubers._"
This passage is part of the first section of "The Waste Land" called "The Burial of the Dead," and it sets the tone for the entire poem, which explores themes of loss, alienation, and the search for meaning in a desolate and spiritually barren world.
