When I was about seven I was very upset by what I discovered years later had been the climax of Menotti's film version of 'The Medium' that I chanced upon on TV. Although written for children, 'Help, Help, the Globolinks!' would probably give them nightmares just as 'Dr Who' and 'Out of the Unknown' gave me at the time.
The plot itself recalls 'The Day of the Triffids', the Globolinks themselves resembling enormous floppy chess pieces repelled by music the way that Slim Whitman disagreed with the Martians in 'Mars Attacks!'. While the big exterior set bears an uncanny resemblance to the desolate Scottish landscape in 'Devil Girl from Mars'; only in bright sixties colours (and this time it's SUPPOSED to look like a set).
I at first took Edith Mathis to be one of the teachers, since wearing a school uniform certainly didn't make her look like a child; while American soprano Arlene Saunders (who sadly recently died of Covid-19) as Madame Euterpova wears a false nose that makes her look like the Child Catcher's sister.
