Target... Earth?

In 1979 I had two film makers Joost and Iris van Rees come to my office when I was working in California. They were making a documentary about the Tunguska Event, asked for an interview. I did it. I did not even know they made the documentary, years later I saw it on television, it is awful, Victor Buono plays Homer the Archivist, he obviously figured out fast that this awful and so he just acts nuts. Here is the weird thing, Googling Target Earth, there are hits where the 1954 film is credited to Joost van Rees who made the 1980 film. And there are places where the poster art for the 1954 film , used on the VHS box turns up as the VHS box for the Target …. Earth? In fact check out IMDb's 'art' for Target…..Earth? It's the one for the 1954 film! Somehow in some crazy way the 1954 and 1980 film have gotten mixed up together.
