 FACT: Towards the end of the episode, Mason reads a report on  Daisys death indicating she died 13 December 1938 in Marietta  Georgia of smoke inhalation. It apparently was common knowledge that  Daisy died on the set of Gone With The Wind (supported in the  Halloween episode by someone who knew her when she was alive). The  filming of the big fire scene in GWTW was 10 December 1938 so the  dates are pretty close. But these early parts of the production of  GWTW (and I believe the rest of the movie as well) were filmed in  Culver City, CA, not Marietta.
