Holocaust 2000 [AKA Rain Of Fire / The Chosen] (1977, dir. Alberto De Martino)

An industrialist leading a nuclear power initiative believes that there are satanic forces supporting his plan. Gleeful The Omen ripoff, complete with a rich cast of second-string familiar faces, Kirk Douglas naked, fun though variable effects work, a Morricone score, and no shame at all.

Here’s the trailer.
