I'm suprised this one hasn't been mentioned....
This used to show up on THE CBS LATE MOVIE quite often, and may have been the inspiration for PREDATOR.
This bubbleheaded alien is wandering around the woods, hunting people. Instead of a gun, he uses these parasitic living shurikens, that adhere to flesh, and noisily slurp out blood and other yummies.
The best part of the movie, though, is the cast....JACK PALANCE and MARTIN LANDAU, trying to out-emote each other, as they bite huge chunks out of the scenery,
LARRY STORCH, doing a hyper-caffienated Corporal Agarn turn as a doomed Scoutmaster, KEENAN WYNN, being , well, Keenan Wynn.
No Robert Vaughn or Christopher Lee, but you can't have everything.
