"Father of all croppies", Colin Andrews is the man who brought the Crop Circles into worldwide attention. During 20 years of research he has experienced mysterious features of the phenomenon as well as the deception and prejudice.
	Busty Taylor has co-operated with Colin Andrews as his pilot and fellow-researcher almost from the beginning. Although not too excited about the latest crop formations, he still has a word to say.
	Dr. Simeon Hein is perhaps the most dedicated investigator of the man-made Circles and their makers. But don't be fooled to think he discredits the paranormal side, far from it...
	Ron Russell is also one of the "croppie veterans". He is an artist who has worked for Nasa and also made illustrations for Sci-Fi TV series. He openly accounts the UFO encounters he has experienced as a member of the CSETI organisation run by Dr. Steven Greer.
	Paul Vigay is a dedicated and broad-minded researcher who focuses on uncensored and free access to all Crop Circle research material. He hosts an international Crop Circle database.
	Lucy Pringle, best known for her excellent aerial photographs, has also conducted a long-term investigation into the Crop Circles' effects on the human body and psyche.
	Matthew Williams is the best known Circle maker, appreciated by some croppies, disliked by most. He claims to have been involved in the making of hundreds of crop formations. But he's had quite extraordinary experiences whilst doing this...
	Nick Nicholson is the editor of the Circular Review magazine. He has been in the scene from the early days and has seen the ups and downs of the Crop Circle scenario.
	Allan Brown has done a lot of geometry research, especially on the Crop Circles in Sussex, his home county. He tends to separate genuine crop formations from man-made ones based on the crop lay quality.
	Tapani Koivula is a Finnish veteran UFO researcher and architect. He has a wide knowledge of UFO related phenomena and sees that many Crop Circle experiences are related to UFO contact cases.
	Well, this is me. I'm Martin Keitel, the writer-producer-editor of this documentary. I have run the FCCI website and lectured about Crop Circles, mostly in Finland since 1997. This is my second documentary on the subject.
