 Invisible Invaders (1959)

Aliens, contacting scientist Adam Penner, inform him that they 

have been on the moon for twenty thousand years, undetected due 

to their invisibility, and have now decided to annihilate humanity 

unless all the nations of earth surrender immediately. Sequestered 

in an impregnable laboratory trying to find the aliens' weakness, 

Penner, his daughter, a no-nonsense army major and a squeamish 

scientist are attacked from outside by the aliens, who have occupied 

the bodies of the recently deceased. (IMDB Doug Sederberg)EL&NV
