I remember watching this film on television in the 70s and loving it. Whilst I'm not quite so impressed by it now, it is still quite a clever sci-fi yarn about an alien species, themselves under dire threat of extinction, who come to earth to assemble a team of scientists to help save their planet from an enemy bent on destroying it. Jeff Morrow has the slightly conical head as "Exeter" - their leader who recruits Rex Reason ("Meacham") and Faith Domergue ("Adams"). It is one of the first of these 1950s films that I recall seeing in colour, and that does render the SFX a little bit dated - perh... read the rest.
