GRIZZLY (1976)

  A giant man-eating bear vs. Christopher George and friends at a camping resort. An obvious JAWS-rip-off that they make even more obvious by the tagline on some of the versions of the poster. A decent time-waster directed by THREE ON A MEATHOOK's creator William Girdler. He would go on next to make the similar animals run amuck epic DAY OF THE ANIMALS which is even goofier than this. Arms, a horse's head and even a little boy's leg are among the appendages lopped off by our super aggressive predator. Crazily enough it was only rated PG when it was originally released. 

 There is a sequel GRIZZLY II: REVENGE which I have never seen and seems to be one of those deals where they ran out of money and never actually finished the film until years later.
