Little Known Horror Flicks

I'm participating in a community experiment over at MovieLens, and the first question was to recommend a little known movie to the group. I couldn't resist selecting a list from my personal collection of horror films. Note, "little-known" in this case, is to horror film buffs:

• Abominable Dr. Phibes, The
• Anguish (Zelda Rubenstein++)
• Biozombie (Japanese zomedy)
• Bloodletting (coming to DVD in Aug/received screener)
• C.H.U.D. (not little-known, but good)
• Cannibal! The Musical (south park creators)
• Day of the Triffids, The (not horror/little-known, childhood fave)
• Dead Hate the Living, The
• Dog Soldiers (not little-known, but good)
• Godmonster of Indian Flats (AHAHAHAHAHAHA)
• Humanoids from the Deep (Corman fare)
• It's Alive! Trilogy (Cohen flicks)
• Premutos: Lord of the Dead (most... deaths... ever!)
• Series 7: The Contenders (not horror, but cynicism)
• Squirm (childood fave)
• Stage Fright (not little-known, but good)
• Syngenor (AHAHAHAhAHAHAHA)
• Unmasked, Part 25 (uhhh...)
• Wicker Man, The (not little-known, but good)
