|This isn't gonna end well: The Night Owl from Stage Fright|
Dario Argento's lost giallo.
A masterful deconstruction of slasher cliches: Behind the Mask: The Rise of Leslie Vernon.
Saw this one on Chiller network. Not a bad one.
Another Italian classic and worth seeking out: Michele Soavi's Stage Fright (aka Deliria and Stage Fright: Aquarius). Death is beautiful in this one.
Two slashers go to war: The OK Freddy vs. Jason
And as a bonus, my favorite slasher movie credit music ever, "The Ballad of Harry Warden" from My Bloody Valentine (1981)
