UFOs: It Has Begun
The Documentary show called UFOs: It has begun is great program hosted by the legendary Rod Serling and Burgess Meredith! The show has many interesting segments of extra-terrestrial activity such as hundreds of UFOs and alien abductions. The real Betty Hill was interviewed here. She and her husband Barney were abducted by alien beings. She explained about the visitors and the sign that one of them showed her. The programed also had about crop circles and more! The footage of the UFOs look legit to Me. This was really a treat that Rod Serling and Burgess Meredith hosted this program. If you love aliens, UFOs, Crop Circles, Rod Serling, Bergis Meredith, and Documentaries this I strongly recommend this DVD! 97 mins
