Now now...it's shameful to try to whack a list with another list..."unsung" and "oddball" are two different things...
"Schlock," by the way, was directly inspired by "Trog"...Landis saw "Trog" and was so amazed at how bad it was that he set out to make a cheap movie that played the idea for laughs.
Here is another one...a short film called "Monkeyland Christmas." This film shows how chimpanzees have Christmas--they don't have it, actually, but the filmmakers dress up a chimp as Santa Claus and put a paper mask on his face to make him look like a human and film him climbing down a chimney into a livingroom. The chimp then slinks around the room dragging a bag of presents, not knowing what to do, and then starts hopping up and down in a monkey kind of way. Then it takes the paper mask off and drags it around the room.
Everyone I have shown this film to has been disturbed and frightened by it. You can buy it on DVD as part of the "Campy Christmas Curiosities" compilation, available at Amazon.
