John Travolta is part of the Scientology cult, which believes humans are exiled aliens called Thetans.

Real UFO discovered in the Travolta movie "Phenomenon"

How about THIS?! A real UFO unwittingly made its way into one of the best Hollywood films of the 1990s, Phenomenon.

If you're unfamiliar with the film, John Travolta's character has a UFO encounter that leaves him inexplicably brilliant. In other words, the experience opens up real human potential inside him that we all have to some degree or another.

But lo and behold, an actual UFO...maybe two (looks like another pops in and out a little lower and to the left)...made it into the released version of the film.
