[EVA] NGE & RahXephon's blue blood: old SF movie reference?

[Gwern Branwen]

While reading through the messy archives, I came across
http://lists.onegeek.org/pipermail/oldeva/1997-August/001893.html
which says:

"## And about "the same type". Anybody notices that when a Shito is
## discovered, the heads-up panel in the control room always says
## "Blood-type: Blue"? I read an EVA book (you know there are many
## of them), and it mentions a Japanese director (forgot his name)
## whose films apparently has had a major influence over Anno (the
## creator of EVA anime). One of his films is a SF movie, in which
## some UFO's appeared in several places on the Earth, and those
## people who were illuminated by the UFOs have their blood turned
## into blue. Nothing else happened to those people. They just
## lived as they were before, except their blood is now blue in
## colour. However, this is not the thing on the governments'
## minds. They are uneasy with certain people who are somehow
## different living in the society. And they fear that they have
## something more sinister developing in their bodies or minds.
## They organised a plot to kill everybody with blue blood. The
## lead character is a government employee, who happens to have
## a girlfriend with blue blood. The story ends in tragedy. All
## the blue-blooded people were killed, and the lead character
## himself killed his girlfriend."

Has anyone see anything in the 13 years since about this? Most of the
regular sources like
http://www.animenewsnetwork.com/answerman/2005-04-15 simply dismiss it
as being just an allusion to nobility.
