As Woodsy mentioned the cult Amicus low budget flick, Terrornauts. Long before Network DVD released it on Blu ray, and Talking Pictures TV screened it, I managed to get hold of it on an American import video version.
Not as memorable as it's Amicus stablemate, They Came From Beyond Space', it's a lot of Saturday morning matinee fun.
As Arto points out some of the toy spacecraft were bought in Woolworths. In the film, another kitbashed spaceship abducts our heroes, and takes them to 'The Wailing Asteroid' , the name of the Murray Leinster novel the film is based on.
On a separate note, comic artist Dennis McLoughlin occasionally used similar toys as inspiration for his Swift Morgan comic strip stories during the late forties, and continuing into the early fifties, which I've already featured on the blog previously.
