The script for the film, originally entitled
Rest House, took five years to perfect. According to Lily Monteverde,
Regal Entertainment decided to enter the film for the
2015 Metro Manila Film Festival instead of another installment of the
Shake, Rattle & Roll series. The budget that would have been allotted for a
Shake, Rattle & Roll film was allotted for
Haunted Mansion instead. All requests of director Jun Lana were granted by Regal and the production design was deemed very expensive by Monteverde. Monteverde said that the film has the biggest budget among the horror entries at the 2015 Metro Manila Film Festival.
Filming Principal photography for the film began as early as April 2015. Director Jun Lana, said that the film is not rushed so it may be improved. The film was shot in
Cabuyao,
Laguna in
Marcos Twin Mansion owned by the
Marcoses. The house was made to look older for the film while the venue was made to look brand-new for the flashback scenes set in the 1950s. A hole as big as a swimming pool was dug for a two-minute scene. Additional shooting days were made for the final touch ups.
Creepy experiences on the set Paolo Gumabao, who plays the character Steve in the movie, shared during the press conference that he, his stylist, and his personal assistant (PA) were "ghost hunting" on the second floor of the mansion on a break from filming. He and his stylist went into a room, only to have the door close behind them –there was no wind and his PA was at the opposite end of the hallway outside. Actress
Ingrid dela Paz said she,
Sharlene San Pedro, and
Eliza Pineda, all heard a little boy talking on the second floor too. Meanwhile, after the press conference, Janella told reporters that her mother and brother were inside a tent when they heard an old man moaning . ==Release==
