Beyond the Darkness (Italian: Buio Omega, lit. 'Omega Darkness') is a 1979 Italian exploitation horror film directed by Joe D'Amato. It follows Francesco Koch (Kieran Canter), an orphaned taxidermist who inherits a house in the woods where he lives with his housekeeper Iris (Franca Stoppi), who is determined to become the new owner. After Iris kills his girlfriend Anna (Cinzia Monreale) with a voodoo curse, Francesco steals her corpse from the local cemetery. He then commits murders connected to his enduring passion for her. A local undertaker (Sam Modesto) investigates and meets Teodora (also Monreale), Anna's twin sister.

Filmed in two weeks in South Tyrol, Beyond the Darkness is a remake of the 1966 film The Third Eye. It was released in Italy to what Italian film historian Roberto Curti described as relatively poor box office, and was re-released in Italy in 1987 as In quella casa Buio omega to associate it with the La casa film series.
