When I was a kid I saw an old B/W movie with Marshall Thompson entitled "First Man In Space" I believe. This movie concerned an astronaut who went into space and got coated with something that caused him to need to suck blood from living people. This was a cheesy plot but far superior to this movie. I've watched "The Incredible Melting Man" three times including the original theatrical release in 1977. I'm still am trying to figure out what it was all about. This movie went the way of the protagonist in the end, ending up in a big pile of unrecognizable crap.
