We've got a truly fascinating conversation on this week's episode with 'Dirty John' showrunner Alexandra Cunningham. Her new show is based upon the wildly popular LA Times true crime podcast of the same name. It deals with deception, seduction, and intrigue. These are all themes found in the film that Alexandra chose to discuss, the 1945 technicolor noir classic Leave Her to Heaven. As 'Dirty John' deals with the mind of a manipulative conman, Alexandra has become somewhat of an expert on the mindset of villains. And she has some enlightening words on Gene Tierney's coldhearted Ellen in Leave Her to Heaven. Alex comes from a playwriting background and explains how she learned to show rather than to tell. April and she dissect the famous drowning scene in the film. And Alex has a fascinating story about working for a suicide hotline, and reveals how sometimes the scariest things happen in the light of day.
