This was a low grade attempt to copy The Day The Earth Stood Still ( a superior sci fi film) with an alien ariving on earth to warn of earth's warlike ways as being seen throughout the universde. Also the scientist and the military disagree on how to handle the situation.
Horror pro John Carradine stars as The Cosmic Man. The cast was first rate with Bruce Bennett, Angela Greene and Paul Langton. But they cannot save this one.
It was enjoyable but nothing more than that. Not a lot of suspense or good special effects.
But it was fun to watch!
