Turkeys to watch after dinner: http://www.horror-wood.com/turkeys.htm
To which I'd like to add:
"Little Shop of Horrors" (the original B/W version with Jack
Nicholson)
"From Hell it Came" (A tree-trunk monster named "Tabonga"
menaces a tropical village. "Are you sure it was Tabonga?")
"Attack of the Mushroom People" (It's kinda like watching
"Survivor" except the losers turn into walking mushrooms.)
"Plan Nine From Outer Space" (Hailed as the worst movie ever
made, it stars Bella Lugosi who had actually died before the film was
made.)
