The Revenant (2015) is a revenge story that's based on the novel about the life of an American frontiersman during the 19th century.
The movie certain embellished some parts of Glass's legacy, but one thing is true—he did cross a great distance, some 200–300 miles (322–483 km), while seriously injured. The bear attack is also true, but the movie leaned heavily on the revenge, while some sources suggest that the real Glass may have actually forgiven those who left him in the wilderness—after all, he was mortally wounded.
