The riveting story of Lee Harvey Oswald and his complex relationship with his overbearing mother Marguerite, “Mama’s Boy” follows Marguerite’s reckless attempts to reunite her family, from Lee’s return to the U.S. from Russia, through the assassination of Kennedy, to her son’s own murder and her defense of his innocence in the months that follow. A fascinating examination of family dynamics and obsessive maternal devotion played out in the shadow of history. The Kennedy assassination serves as a framework for “Mama’s Boy,” but the play isn’t overtly political, or intended to change public opinion.
