Grizzly 1976.
An 18ft tall grizzly bear attacks a state park and a park ranger efforts are hammered by other hunters to stop it.
This has always been a good monster on the loose in the woods film, it is what you would expect it to be a certain B movie but does hold up with its action, suspense and well crafted actors from Christopher George (City Of The Living Dead) Andrew Prine (Eliminators) and Richard Jaeckel (Starman) as the park rangers. It's brilliantly directed by William Girdler (The Manitou) and has great cinematography. Worth a watch it's Jaws With Claws.
