Parasyte is an anime that’s being adapted into two live-action films. The anime is currently showing in Japan and streaming via Crunchyroll internationally.
The anime is a horror. The alien creatures have a hunger for human flesh and need a human host to survive. High school student Shinichi Izumi knows their secret because his right hand has been taken over by a parasite called Migi. The two find themselves caught in a war between humans and parasites.
The live-action films are being directed by Takashi Yamazaki (Space Battleship Yamato) and the first is due out in November 2014 with the second in April 2015. No word as to whether they’ll escape Japan and air elsewhere yet.
