The 1966 horror film Incubus has developed the reputation of being a cursed film. The William Shatner-starring picture attempted to tap into a wider international market by having its dialogue consist entirely of the language Esperanto, a constructed language (one consciously created by linguistics instead of evolving naturally) developed in the late 1800s by a Russian linguist in the interest of promoting peace and fostering international understanding. The legend of Incubus' curse began when one of the film's stars, Milos Milos, killed his girlfriend and himself nine months before the film premiered. To make matters worse, when the film premiered, the Esperanto-speaking audience it attempted to cater to largely ridiculed the feature for the cast's poor pronunciation of the language. The little-loved oddity then became lost when its original print burnt in a fire. Years later a copy of Incubus was discovered in the Cinémathèque Française. The SyFy channel funded a painstaking restoration in 2001 and now audiences can enjoy the bizarre spectacle of Shatner bringing his unique style of line delivery to dialogue he isn't capable of pronouncing correctly. There's our list of films that were almost lost forever. Did we miss any notable examples? Let us know in the comments.
