15. The role of addiction is a major factor in much of the distress in Rex's life in both the book and
movie versions of The Glass Castle. The movie
suggests that Rex's problems as an adult are the
result of abuse as a child as well as growing
up in poverty. Throughout the movie, book, and all of
his life, Rex fought his own demons. In your opinion are
demons like these the result of external
circumstances or internal turmoil? Why do troubles
such as these often lead to addiction? Can
addiction be overcome? What might have
helped Rex to make lasting changes in his life? Can a
person truly change who he is? Defend
your answer.
