‘The Revenant’ was a box office breaking movie and most reviews are that it was very good. In the movie the Leonardo DiCaprio character gets attacked and mauled by a mean mother grizzly bear. It is a riveting scene. But not the best bear attack scene in movies. Back in 1997 a movie was released called ‘The Edge.’ It received little fanfare and sort of faded away into oblivion. A few years ago I caught it on TV and was mesmerized.
The survivors are stranded in the Alaska wilderness and ultimately get stalked and attacked by a giant Kodiak bear. This Kodiak (Kodiaks are giant grizzlies) chases them for miles and the characters barely escape until the final showdown. Sensational bear attack scenes.

The Edge is a 1997 American survival drama film directed by Lee Tamahori and starring Anthony Hopkins and Alec Baldwin. Bart the Bear, a trained Kodiak bear known for appearances in several Hollywood movies, also appears in the film as a vicious grizzly; this was one of his last film roles.
