Extras spent two twelve-hour days in the water as ghouls.

At one point in the movie, the deceased Chris forces the living Annie to write his name while she is writing in her diary. According to supernatural investigators, this is called Automatic Writing, a technique in which living people blank their minds to have it empty of thoughts, allowing a ghost or spirit to use the hand of the living to write messages from the afterlife. It was shown in The Changeling (1980).
The main plot is a modern version from the Greek myth of Orpheus. According with it, Orpheus was Thrace's king who fell in love with a forest nymph called Eurydice. Using his special talent for music (he was considered the best music ever between mortals, as well as Apollo was it between the gods), Orpheus conquered Eurydice's love and he married her. Time later, when Eurydice was visiting his fellow nymphs in the forest, she was pursued by Aristaeus, Apollo's grandson and Hunters' god, who tried to force her. Escaping from him, Eurydice was bitten by a poisonous snake, dying quickly. Orpheus, turned crazy for the lost, taken his lyre and he traveled to the underworld of Hades (Greek's Afterlife), in order to ask to the god Hades to recover Eurydice's soul to resurrect her. After to convince Charon (Hades' ferryman) to cross the Stygia river that separates the living world from the land of the dead, and to defeat Cerberus (Hades' guardian, a three-headed dog) using his music, Orpheus arrived at Hades' palace, seducing to the god of the dead and his wife Persephone to accept his petition. Hades put the condition that he would must walk to the Hades' exit not turning back for looking Eurydice, who would walk a few steps behind him. If he never looked her until to leave land of the dead, she would live again. Orpheus tried to accomplish the mission, but he doubted when he was a few steps of the exit, losing her again when he turns back to verify if Hades' had lied to him. According an extended version of the story, Orpheus wandered by Greece to meet the Muses, nine daughters of Zeus and Mnemosyne, joking them in bad terms. Get angry, the muses killed Orpheus violently and broke his lyre against a stones. Zeus, touched by his death, met Orpheus with Eurydice in Elysium Fields (the side of the Hades reserved to good souls), meanwhile his lyre was converted in the Lyra constellation as remembrance of them story. It was the inspiration of the cult called Orphic Mysteries or Orphism.
