Grizzly (1976)

Description   [from Freebase]

Grizzly (also known as 'Killer Grizzly') is a 1976 horror film directed by William Girdler. The film is about an 18-foot man-eating Grizzly bear that terrorizes a National Forest. The film stars Christopher George, Andrew Prine and Richard Jaeckel. Widely considered a Jaws rip-off, Grizzly used many of the same plot devices as its shark predecessor, a huge box office success during the previous year 1975. In 1983, a sequel Grizzly II: The Predator was planned and shot, but never released and provided early roles for both Charlie Sheen and George Clooney. The giant grizzly bear in the film was portrayed by the mother of Bart the Bear. The film opens with a military veteran helicopter pilot and guide Don Stober (Andrew Prine) flying individuals above the trees of a vast National Park. He states that the woods are untouched and remain much as they did during the time when the Native Americans lived there. Two female hikers are breaking camp when one of them is attacked and killed by a bear. The second woman finds apparent safety within a nearby cabin until the bear tears down a wall to reach her.
