I've been reading up on George A. Romero over the past few days. In Paul Gagne's book The Zombies that Ate Pittsburgh he quotes Romero about working on Umberto Lenzi's giallo Spasmo, adding some new footage to spice up the American version:
"It was really nicely shot, and very rich looking. In the Italian version, you never saw the killer actually doing the killings, so we added about ten minutes showing the kills." (p. 68)
Has anyone out there seen this version and how well or badly does Romero's footage integrate with the film as a whole? Is this version available anywhere?
