The 27th Day is a 1957 Cold War science fiction B-movie. However, don’t let the B-movie label turn you off. I think it’s quite good. It features an intelligent script and good acting.
It's difficult to find it on Region 1 DVD. However, it has recently been uploaded to YouTube. I don’t know how long it will be there before it gets yanked, so you may wish to download it.
The screenplay is by
John Mantley, who adapted it from his novel.
The director is
William Asher, who has quite a resume in both movies and TV.
It stars
Gene Barry.
The actor with the great voice who plays the alien is
Arnold Moss. He played Kodos the Executioner in the
Star Trek: TOS episode,
The Conscience of the King. Another good voice actor,
Paul Frees, makes a brief appearance as the American TV newscaster. This is a rare onscreen role for him. He voiced the unseen John Beresford Tipton, in the 1955-1960 TV series,
The Millionaire.
The movie been uploaded to YouTube in eight parts. It runs about 75 minutes:
