The Elvis song foreshadows part of the movie(spoiler)
The Elvis song "In the Ghetto" was heard twice in the movie but after listening to the lyrics closely I think I might know why. The lyrics that I think relate to the movie:
"Then one night in desperation, the young man breaks away"
"He buys a gun" (Doesn't actually buy it, but uses one to try to rob the bank)
"Steals a car" (Yep)
"Tries to run, but he doesn't get far" (Tries to run away with Iris, but when she won't come he keeps going and is caught by the police)
Am I reading too much into this? Thoguhts?
