Virus (otherwise known as Fukkatsu no hi, lit. Day of Resurrection, Virus) is a 1980 post-apocalyptic sci-fi movie directed by Kinji Fukasaku and starring Masao Kusakari, George Kennedy, Robert Vaughn, Chuck Connors, Olivia Hussey, Edward James Olmos, Ken Ogata, Sonny Chiba and Glenn Ford. The film is notable for being the most expensive Japanese film ever made at the time.
The movie opens with a British nuclear submarine called the HMS Nereid entering Tokyo Bay in the then-future of December 1983. The ship’s crew and Japanese seismologist Yoshizumi (Masao Kusakari) send a reconnaissance drone to search the city for any survivors, only to find decayed bodies. It also gathers air samples of something called MM88. .
