My Favorite Martian was an enjoyable waste of time. Starring Ray Walston as a man from Mars who had crash-landed on earth, and Bill Bixby, as Tim, the young newspaper reporter who found him. Tim saw dollar signs, fame and fortune in his eyes when he found a Martian, but unfortunately, never did get to tell his story, in spite of the fact that this Martian moved in with him. You see, the Martian, who passed himself off as Tim's Uncle Martin, would not admit to anyone but Tim what he really was, and Tim would have appeared crazy to insist that Martin was REALLY a Martian!
Martin had some interesting powers: he was able to turn invisible by raising some pretty cheesy looking antennae from the back of his head; he could also point at something and make it lift and come to him. He was also able to read minds, and had a vast knowledge of technology. Apparently the Martians were much more advanced than we were.
The show lasted for three seasons on CBS, giving lots of time for Tim and Martin to have some interesting adventures, all the while trying to repair his ship and return home to Mars. Like ALF some years later though, he never quite made it.
