The Night Stalker. A killer is stalking Las Vegas, leaving his victims completely drained of blood and investigative reporter Carl Kolchak (the great Darren McGavin) is soon convinced that the killer is not just some madman who thinks he's a vampire but an actual real life creature of the night. This early 70s US TV movie that led to a sequel movie and eventually a TV series, which in turn later inspired The X Files, stands up very well and is very entertaining and spooky fun, with McGavin a hoot as the irascible reporter who just can't help getting up the noses of anyone in authority.
