i collected unusual versions of Friday the 13th movies in the late 90's,I have never found a alternative version of part 3.
These were/should be available at your local record fair lol
Part 4 Uncut-Release version with the TV version non gore added but has the uncut nurse decapitation included
Part 5 Version 2-Has all the swearing removed and different angles/dialog,i prefer this version
Goes to hell-Turns in to a different film after the 1st 10 mins,this version has more gore and is a better movie unfortunately the version in the wild is taken from a VHS dupe with the tracking out
