movie inspired by then Velikovsky fad
Velikovsky, Jewish-Russian intellectual, psychologist and writer, published in 1950 a book: WORLDS IN COLLISION, which spurred a series of 'collision' movies.
In order to justify accounts of catastrophes in ancient literature -both Jewish & non-Jewish-, Velikovsky explained a series of planetary catastrophes such as planets crossing orbits, Venus being originally a comet, Earth as former satellite of a proto-planet. Naturally he was never taken seriously and mostly acted later in life as new age guru for those who read his theories figuratively.
