The dildo was a fun prop during the shootings, not as fun though as the penis replica that was used in a gory scene near the end of the movie. The actors who fell asleep during the shootings became victims of parody photographs with the penis prop on their faces.
The original location has been canceled during the day of the first shooting. A different place has been found, thanks to a close friend. All of the original production design had no use in the new place, due to the fact that the original mansion was the key ingredient for this movie to work. A small forest was also located outside the original mansion, which made all the chase scenes to be eliminated, creating a cheaper vision. The new place was also smaller and wasn't good enough for any movie, due to the fact that there were large windows everywhere and very small rooms. Two of the rooms inside the movie don't belong to the main mansion at all.
The first shooting lasted about 48 hours with no pause at all. The actors who weren't evolved in a scene were actually in between takes to recover. The movie needed a larger crew to achieve that type of guerrilla film-making. The "torture" scenes took place inside the studio (MacabroFilms). The movie was completed in 14 days.
