A Dead Little Sister was the direct cause of their 'conversion' to atheism, as well as a paradoxical anger at a God who lets such things happen. Consequently, the Hollywood Atheist can easily be made to reverse or reexamine their lack-of-belief if something good happens, even if nothing explicitly supernatural is going on. Conversely, when something bad happens (especially their own death approaching) the atheist will suddenly become a believer and start praying for help. Apparently, there are no atheists in foxholes.
