The Day Mars Invaded Earth

The Day Mars Invaded Earth, A scientist, the brains behind a Martian probe, returns to his wife and family because things are starting to fall apart in the marriage. They are currently living in a part of a mansion. Once there, strange events occur. He is walking around when he sees his wife, but she doesn’t respond to him. When he sees her later, she says she has been in the house all along. Soon there is an opposite event with her seeing him as a threat. The children are affected too. We are finally let in on things. Doppelgangers of these people have formed from a kind of energy scan. At one point, the handsome young boyfriend of the teenage girl is killed when he crashes his car trying to avoid her on the road. This copy later appears in the girl’s bedroom. What can they do? This has some tight suspense. The down side would be that it gives its principle characters little or no power to counteract what is going on. By the way, if I had seen this as a young child, I would have not slept for a week.
