Incubus ★★ 1965
One of the very few films made in the artificial language of Esperanto (so it's subtitled in English). Beautiful Kia (Ames) and Amael (Hardt) are sisters who retain their youth and beauty by sucking the life out of the corrupted souls who visit a supposedly magic well. Then Kia discovers the uncorrupted soldier Mark (Shatner) and falls big time. But her succubis sis doesn't like what's going on and casts a spell that calls an incubus to wreak havoc. Creepily atmospheric with striking cinematography by Hall. 76m/B VHS, DVD . William Shatner, Allyson Ames, Eloise Hardt, Ann Atmar, Robert Fortier, Milos Milos; D: Leslie Stevens; W: Leslie Stevens; C: Conrad L. Hall; M: Dominic Frontiere.
