“Award winning film-maker Terje Toftenes who made the documentary “Crop Circles: Crossovers From Another Dimension” appeared unexpectedly via Skype on Circlemakers TV during the show this week (May 18th, 2011).
Terje told the show host Matthew Williams that he became interested and involved in crop circles in 2002 and had been convinced they were not made by people. His film received awards but now he felt foolish and embarrassed he said but went on the congratulate the people making them because they had made such a good job of them. Â He told Matthew that he thought it was time for the truth about all this to be told and went on to say that he was equally convinced now that there were also strange things happening around the circles.”
