Lead actress Gretchen Barretto turned down the film without reading the script when it was first offered to her since she did not want to shoot at the hotel due to its reputation. Then someone convinced her to read it first. She read it that morning and called the producers in the afternoon. She was going to do it on a couple of conditions - to bless the place first and no one could talk about ghost stories on set.
Actor Abe Pagtama took the role that Christopher Ad. Castillo's late father, Celso, was supposed to play.
