William Shatner, the beloved Canadian actor known for playing Star Trek‘s Captain Kirk, has been especially vocal about his belief in all things paranormal. In a 2010 interview with the Montreal Gazette (not currently available online), he said, “There is no doubt that there is life out there; the mathematics of it lead you to that absolute conclusion. In my mind, there is no doubt that the universe teems — teems! — with life in all its forms.” Though Shatner once claimed he saw UFOs after crashing his motorcycle in the desert, in his autobiography he confesses that he lied about that. So maybe he hasn’t had any first-hand encounters with aliens, but he certainly believes in them.
