saw this movie on TV in the 70’s. I believe there were small flat creatures that would attack from the trees. In one scene, they had to cut off a guys arm to try to save him and the special effect was just a solid plastic arm with a hole in the center that blood came out of. would like to see again.
Island of Terror (1966)? But… trees?
“Island of Terror”(1966)?
The creatures aren’t really flat, but they drop from trees or tops of houses. Click on the link below for the hand chopping scene.
