The Midwich Cuckoos (made by Hollywood as “The Village Of The Damned”)
I’ll think you will find that that is a remake of the 1950’s British Film of the same name. (along with the Italian Job, Get Carter etc.. Holywood being the home of recycling )
But by all means take a look at the original, and the follow up ‘Children of the Dammed’.
