Every weekday, we recommend a podcast related to a movie or TV show you can watch at home: For as long as crop circles have appeared, there have been theories as to who wss creating them—drunken pranksters, crop artists, and even…time-travelers. For more episodes like this one, subscribe to Unexplained Mysteries on Spotify. Also, check out the film Signs, which is now available to stream!
