The Second Volume in the X-Files Mythology series, covers one of The X-Files' weirder concepts: the alien being that travels from host to host, occasionally revealing itself as it travels across a person's eyeballs. What's Michael got to do with all this? Errm... I don't know, but he looks darn cute!
This movie series isn't even credited on the IMDB website, but can be bought on Amazon.com (Region 1 DVD only - Canada and Usa)
