The Darby House was used as the "attic house" in the movie. It's the oldest standing building in the town of Dawson Springs KY.
Built in 1886, it looks very much today as it did over 100 years ago.
The flannel shirt worn by "Running Woman" was also used in the movies "Hell is Full" & "The Caretakers"
The Club Fun scenes were filmed in a building that was once the Anton KY elementary school.
The Lab Scenes were filmed in Hopkins County Central High School. They planned on using a room in a different part of the building and accidentally discovered the room used in the movie, the morning of shooting. It was so perfect, they moved the shoot there that very day.
Take a look at the entire cast list and see if you notice any similarities to a certain classic television show.
