Ghost Fever was made in 1985, and starred Sherman Hemsley (of The Jeffersons fame) who also funded it. The film didn't get a American release til 1987, two years after it was produced. It is only related in the name of the Italian version, but it does have them trying to deal with the ghosts and ultimately battling a Vampire that wants to use their bodies for zombie parts. The film makes a direct reference to Ghostbusters from character Buford: "Do you realize I can make one phone call and bust this whole god damn place?!"
