The Day the Earth Stood Still ( 1951 ) - 3 1/2 stars out of 5 stars

We'll end this 50's trip down sci-fi lane with a film again,that was remade later,but for it's time had a stellar cast.British actor Michael Rennie as a alien visitor,Klaatu. Future academy award winning actress Patricia Neal as Helen Benson and legendary actor Sam Jaffe as Professor Jacob Barnhardt  head the fine cast.Released in 1951 and running a short 92 minutes,I took 1 and 1/2 stars off because its in black and white and I don't really think aliens would be so benevolent.The robot"inforcer"is tame by todays standards as well and the film is a little dated.Still its good fun so check it out.Trailer URL follows the pix.IMDB summary below.

An alien lands and tells the people of Earth that they must live peacefully or be destroyed as a danger to other planets.
