The bar where the film was shot is known to be haunted in real life by the spirit of a man who was burned alive in a kitchen fire decades ago. Strange noises are often heard, especially at night, and sometimes the smell of something burning is prevalent in the air.
The story idea was created by the writer's teenage daughters after hearing their mother's ideas for a horror film and deciding it was stupid.
Because the bar has been closed for several years, there was no actual drinkable liquor on the set, much to the disappointment of the cast and crew.
