On Milos Milos, the fellow who played Incubus:
In 1966 he shot and killed the estranged wife of Mickey Rooney, Carolyn Mitchell Rooney, and then killed himself.
Weird. Just weird.
And on Eloise Hardt, the woman who played Amael:
Her daughter with ex-husband Hans Habe was kidnapped and murdered on 30 December 1968. Her killing was never solved. She was 17.
